U.S. Route 1 (US 1) is a major north–southU.S. Route, extending fromKey West, Florida, in the south toFort Kent, Maine, at theCanada–United States border in the north. In theU.S. state ofPennsylvania, US 1 runs for 81 miles (130 km) from theMaryland state line nearNottingham northeast to theNew Jersey state line at theDelaware River inMorrisville, through the southeastern portion of the state. The route runs southwest to northeast and serves as a majorarterial road through the city ofPhiladelphia and for many of the suburbs in thePhiladelphia metropolitan area. South of Philadelphia, the road mostly follows the alignment of theBaltimore Pike. Within Philadelphia, it mostly followsRoosevelt Boulevard. North of Philadelphia, US 1 parallels the route of theLincoln Highway. Several portions of US 1 in Pennsylvania arefreeways, including from near the Maryland state line toKennett Square, the bypass ofMedia, the concurrency withInterstate 76 (I-76, Schuylkill Expressway) and theRoosevelt Expressway in Philadelphia, and betweenBensalem Township and the New Jersey state line.

US 1 enters Pennsylvania fromMaryland inWest Nottingham Township,Chester County, heading northeast as a two-lane undivided road that soon widens into a four-lanedivided highway. The road curves north and runs through fields and woods with some development, becoming a four-lanefreeway that is called the Kennett–Oxford Bypass and dedicated as the John H. Ware III Memorial Highway. The route runs through rural land with some nearby homes and commercial development, coming to apartial cloverleaf interchange withPennsylvania Route 272 (PA 272) west of the community ofNottingham. From here, US 1 curves to the northeast and continues intoEast Nottingham Township, passing through a mix of farmland and woodland with some residences. The freeway skirts into the western portion of the borough ofOxford and reaches adiamond interchange withPA 472 that serves the borough. The route runs through more rural areas with some nearby development and entersLower Oxford Township, where it bends to the east-northeast and comes to a partial cloverleaf interchange withPA 10 that also provides access to Oxford. US 1 continues through farmfields and woods and crosses the West BranchBig Elk Creek before it heads intoUpper Oxford Township, where it has a partial cloverleaf interchange withPA 896.[2][3]
The freeway crosses Big Elk Creek intoPenn Township and heads east to a diamond interchange atPA 796 north of the community ofJennersville. The route passes through a mix of fields, woods, and residential development as it continues east intoLondon Grove Township and crossesMiddle Branch White Clay Creek before it comes to a partial cloverleaf interchange atPA 841 north of the borough ofWest Grove. US 1 curves northeast and reaches a diamond interchange servingPA 41 northwest of the borough ofAvondale. The freeway continues through rural land with some development and bends to the east, crossing theEast Branch White Clay Creek, heading intoNew Garden Township, and coming to a partial cloverleaf interchange at Newark Road north of the community ofToughkenamon. The route heads through wooded areas with some nearby residential development and crossesWest Branch Red Clay Creek before it skirts into the southern portion ofEast Marlborough Township, where it has a diamond interchange withPA 82 north of the borough ofKennett Square. From here, US 1 continues east and entersKennett Township, where it crossesEast Branch Red Clay Creek and passes near more development, coming to the northern terminus of the freeway at a southbound exit and northbound entrance with theBaltimore Pike.[2][3]
At this point, US 1 continues northeast along the four-lane divided East Baltimore Pike into East Marlborough Township and passes businesses, widening to six lanes. Along this divided highway stretch of US 1, a few intersections are controlled byjughandles. The road narrows to four lanes and passes near homes and businesses, before coming to an interchange that provides access toLongwood Gardens and the Brandywine Valley Tourism Information visitor center to the north of the road, at which point it crosses back into Kennett Township. A short distance later, US 1 comes to an intersection withPA 52, at which point that route heads onto the East Baltimore Pikeconcurrent with US 1. The road heads into wooded areas with some homes and businesses, at which point PA 52 splits in the community ofHamorton to continue southeast toward the city ofWilmington, Delaware. The route turns to the northeast and crosses intoPennsbury Township, where the official name becomes Baltimore Pike. The road curves to the east again and passes through more woodland with some residential and commercial development, crossing anEast Penn Railroad line at-grade before heading across theBrandywine Creek.[2][3]
Upon crossing the Brandywine Creek, US 1 continues intoChadds Ford Township inDelaware County and passes to the north of theBrandywine Museum of Art. The route heads into the community ofChadds Ford and comes to an offset intersection with Creek Road in a commercial area. The road continues through wooded areas with some development, passing to the south ofBrandywine Battlefield. The route curves northeast and heads into areas of businesses, intersectingUS 202/US 322 inPainters Crossing. Here, US 322 heads north along US 202 and turns east to join US 1 in a concurrency along Baltimore Pike, running past more commercial establishments inConcord Township. InConcordville, US 322 splits to the southeast and US 1 continues along Baltimore Pike, intersecting Concord Road before heading into more wooded areas with occasional businesses and crossing theWest Branch Chester Creek.[2][4]
The route curves to the east and enters the borough ofChester Heights, running past businesses before heading into forested areas, where it passes north of the corporate headquarters ofWawa. The road turns northeast and crosses theChester Creek intoMiddletown Township. The route passes underSEPTA'sWest Chester Branch northwest ofWawa Station, which serves as the terminus of SEPTA'sMedia/Wawa Line. US 1 heads through the community ofWawa and continues into commercial areas, coming to an intersection withPA 452 in the community ofLima. Following this, the route continues east and passes between thePromenade at Granite Run residential and retail center to the north and Riddle Hospital to the south, coming to an interchange withPA 352. A short distance later, US 1 splits from Baltimore Pike at an interchange by heading northeast onto the Media Bypass, a four-lane freeway which bypasses the borough ofMedia to the north. The Baltimore Pike interchange is a northbound exit and southbound entrance that also features aU-turn ramp from northbound US 1 to southbound US 1. US 1 runs through wooded areas with some nearby homes and crossesRidley Creek intoUpper Providence Township. The freeway continues northeast before it curves to the east and comes to a diamond interchange atPA 252 in the community ofRose Tree. The route runs through more wooded areas with some homes and reaches a southbound exit and northbound entrance at State Road. Following this, US 1 crossesCrum Creek intoMarple Township and comes to athree-level diamond interchange atI-476.[2][4]
Past the I-476 interchange, US 1 continues east and heads into business areas, where the freeway ends and the route becomes four-lane divided South State Road, passing south of a shopping center. The route crosses intoSpringfield Township and reaches a diamond interchange withPA 320, with the southbound exit providing access to the shopping center. The road continues into residential areas and becomes North State Road upon crossing Springfield Road. US 1 curves northeast and crossesDarby Creek intoUpper Darby Township, where it heads into business areas. State Road splits to the northeast and the route becomes Township Line Road, which heads north intoDrexel Hill as a four-lane undivided road through residential neighborhoods. The road passes commercial development and curves to the northeast, forming the border betweenHaverford Township to the northwest and Upper Darby Township to the southeast. US 1 continues past homes as it heads through Drexel Hill, crossingDrexel Avenue and passing to the southeast of theLlanerch Country Club. The route heads into the community ofLlanerch, where it gains acenter left-turn lane and passes between a shopping center to the northwest and residences to the southeast. The road crossesNaylors Run andDarby Road/Lansdowne Avenue before it reaches an intersection withPA 3 a short distance later. From here, US 1 becomes a four-lane undivided road and continues northeast past residences and a few businesses before passing northwest of a golf course. The route passes over SEPTA'sNorristown High Speed Line south ofTownship Line Road station before it comes to a bridge overCobbs Creek.[2][4] Upon crossing Cobbs Creek, US 1 runs along the border between Haverford Township in Delaware County to the northwest and the city ofPhiladelphia inPhiladelphia County to the southeast, passing between homes to the northwest and a golf course to the southeast.[2][4][5]
_at_the_exit_for_Presidential_Boulevard_NORTH_along_the_border_of_Philadelphia_and_Lower_Merion_Township%2c_Montgomery_County%2c_Pennsylvania.jpg)
The route becomes known as City Avenue and colloquially as City Line Avenue and forms the border betweenLower Merion Township inMontgomery County to the northwest and the city of Philadelphia in Philadelphia County to the southeast, at which point it continues northeast as a five-lane road with a center left-turn lane past residential areas to the northwest and businesses to the southeast. The road crosses Haverford Road and continues through wooded residential areas, with the suburban community ofPenn Wynne to the northwest and the Philadelphia neighborhood ofOverbrook to the southeast. Along this stretch, the route crossesWest Branch Indian Creek. US 1 passes to the southeast ofLankenau Medical Center before it crossesEast Branch Indian Creek and reaches an intersection withUS 30 (Lancaster Avenue). Past this intersection, the route runs betweenSt. Charles Borromeo Seminary to the northwest and residential development to the southeast before it passes overAmtrak'sKeystone Corridor railroad line north ofOverbrook station, which servesSEPTA'sPaoli/Thorndale Line. The road continues past mixed residential development before heading through the campus ofSaint Joseph's University. US 1 becomes lined with businesses as it passes between the Lower Merion Township community ofBala Cynwyd to the northwest and the Philadelphia neighborhood ofWynnefield to the southeast. The route comes to a bridge over SEPTA'sCynwyd Line south ofBala station before it reaches an intersection with the eastern terminus ofPA 23 and Conshohocken Avenue. The road passes more commercial development as it heads southeast of the Bala Cynwyd Shopping Center and crosses Belmont Avenue, where it passes north of the Belmont Reservoir. US 1 becomes a four-lane divided highway and heads past businesses and office buildings, passing between the formerWCAU studios to the northwest and theWPVI-TV studios to the southeast prior to the Monument Road intersection.[2][5][6]
US 1 comes to an interchange withI-76 (Schuylkill Expressway), at which point City Avenue heads across theSchuylkill River on theCity Avenue Bridges to an interchange withRidge Avenue,Lincoln Drive, andKelly Drive and US 1 heads southeast concurrent with I-76 on the Schuylkill Expressway, an eight-lane freeway that fully enters Philadelphia and runs between the West Falls Yard onNorfolk Southern Railway'sHarrisburg Line and the river to the north and wooded areas ofFairmount Park to the south.[2][5]
US 1 splits from I-76 by heading northeast on the Roosevelt Expressway, a six-lane freeway. Immediately after the split, the route heads onto theTwin Bridges, which carry the route over Norfolk Southern Railway's Harrisburg Line, a wye connection between the Harrisburg Line andCSX Transportation'sTrenton Subdivision railroad line that uses thePhiladelphia and Reading Railroad Schuylkill River Viaduct; Martin Luther King Jr. Drive; a trail; the Schuylkill River; theSchuylkill River Trail; Kelly Drive; and Ridge Avenue. From here, the freeway heads into theEast Falls neighborhood and passes near urban residential and commercial development, coming to a southbound exit and northbound entrance serving Ridge Avenue and Kelly Drive. US 1 crosses under SEPTA'sManayunk/Norristown Line and continues through developed areas, heading to the southeast of Queen Lane Reservoir. The route comes to a southbound exit and entrance that serves Fox and Henry avenues. The freeway passes over SEPTA'sChestnut Hill West Line as it comes to an interchange with Wissahickon Avenue, which also provides access toGermantown Avenue and Hunting Park Avenue, in theNicetown–Tioga neighborhood. Here, the freeway narrows to two northbound lanes while retaining three southbound lanes. US 1 heads intoNorth Philadelphia and crosses through Fernhill Park before it curves east and comes to a bridge over SEPTA'sMain Line and CSX Transportation's Trenton Subdivision north of SEPTA's Roberts Yard and south ofWayne Junction station serving the SEPTA line. The route continues along the bridge over urban neighborhoods before it descends into a cut as a four-lane freeway, with a northbound exit and southbound entrance servingPA 611 (Broad Street), provided viafrontage roads (St. Lukes Street northbound and Cayuga Street southbound). The freeway passes under PA 611 (Broad Street), which also carries SEPTA'sBroad Street Line subway. Past this interchange, US 1 comes to a southbound exit and northbound entrance withUS 13 (Roosevelt Boulevard) north of theHunting Park neighborhood, where the Roosevelt Expressway ends.[2][5]
At this point, US 1 becomes concurrent with US 13 on Roosevelt Boulevard, a wideboulevard withlocal–express lanes that has 12 lanes total in a 3–3–3–3 configuration. Along Roosevelt Boulevard, access between the inner and outer carriageways is provided with narrow crossover ramps immediately between them; for most intersections, left turns are only permitted from the inner pair (or from separate left turn roadways) and right turns only from the outer, and crossing between them is not permitted at the intersections. There arespeed cameras along the boulevard and many intersections also havered light cameras. The boulevard continues past urban residential neighborhoods, coming to the 5th Street junction, where the local lanes intersect the street at-grade and the express lanes pass over the street on a bridge. US 1/US 13 continues east and passes through theFeltonville neighborhood, where it intersects Rising Sun Avenue, before it crossesTacony Creek. At this point, Roosevelt Boulevard continues intoNortheast Philadelphia and curves to the southeast at an intersection with Adams and Whitaker avenues, passing between a shopping center to the northeast andFriends Hospital to the southwest. The boulevard curves to the northeast again at a junction with Adams and Summerdale avenues, passing near rowhouses before reachingOxford Circle. At this point, the local lanes pass through Oxford Circle, atraffic circle atCheltenham Avenue, Castor Avenue, and the southern terminus ofPA 232, which runs along Oxford Avenue. The express lanes pass under Oxford Circle. Past the circle, Roosevelt Boulevard continues east-northeast through residential areas.[2][5]
The road crosses Bustleton Avenue and US 13 splits from US 1 by heading southeast on theone-way pair of Robbins Street northbound and Levick Street southbound, while US 1 continues northeast along Roosevelt Boulevard past urban homes and businesses. The boulevard bends to the northeast after crossing Harbison Avenue and continues through developed areas in theMayfair neighborhood. The route comes to an interchange withPA 73 (Cottman Avenue), where the local lanes intersect PA 73 while the express lanes pass under it. Ramps provide access from the express lanes to the local lanes prior to the PA 73 junction in each direction. Past here, US 1 passes to the southeast ofRoosevelt Mall before it curves north and runs near more residential and commercial development. The boulevard turns to the northeast and heads east of theRhawnhurst neighborhood, crossing Rhawn Street before reaching an interchange with Solly Avenue/Holme Avenue at the former Pennypack Circle, where the local lanes intersect Solly Avenue/Holme Avenue while the express lanes head under the street. Following the interchange, the route runs to the west ofNazareth Hospital before it heads into wooded areas ofPennypack Park, where it passes overPennypack Creek and the parallel Pennypack Trail.[2][5]
After passing through the park, US 1 heads through residential areas, before running past businesses and coming to an intersection with the southern terminus ofPA 532 at Welsh Road. The boulevard becomes lined with more commercial development and crosses Grant Avenue, which provides access toNortheast Philadelphia Airport. The route runs between a residential neighborhood to the northwest and a shopping center to the southeast before it passes northwest of Northeast Philadelphia Airport and heads past more commercial establishments, running parallel to an East Penn Railroad line to the east of the road. After this, the road comes to an intersection withPA 63 at Red Lion Road. At this point, PA 63 becomes concurrent with US 1 on Roosevelt Boulevard, and the boulevard heads northeast through areas of businesses and industrial parks. After intersecting Byberry Road, the concurrency with PA 63 ends at an unfinishedcloverleaf interchange with Woodhaven Road, where PA 63 heads southeast onto the Woodhaven Road freeway. US 1 continues northeast past industrial parks, intersecting Southampton Road, before it passes to the west ofBenjamin Rush State Park. At this point, the local and express lanes merge, and the route becomes a divided highway with three northbound lanes and four southbound lanes that crossesPoquessing Creek.[2][5]
Upon crossing the Poquessing Creek, US 1 leaves Philadelphia and entersBensalem Township inBucks County. At this point, the road becomes theLincoln Highway, heading past businesses and narrowing to six total lanes at the Old Lincoln Highway intersection. Further northeast, the route becomes a freeway before coming to a partial cloverleaf interchange withPA 132. A short distance past PA 132, the road reaches the Bensalem interchange with thePennsylvania Turnpike (I-276); this interchange is a doubletrumpet interchange and also includes a direct ramp from Horizon Boulevard to the Pennsylvania Turnpike. From here, US 1 becomes the Martin Luther King Jr. Memorial Highway and passes near several businesses before coming to a partial cloverleaf interchange with Rockhill Drive, which provides access to theNeshaminy Mall to the east of the road. The route passes between an office park to the west and the shopping mall to the east before it heads into wooded areas and crossesNeshaminy Creek. Upon crossing the creek, the freeway heads intoMiddletown Township and comes to a northbound exit and southbound entrance with the southern terminus ofUS 1 Business (US 1 Bus.). At this interchange, the freeway narrows to four lanes. From here, US 1 passes over CSX Transportation's Trenton Subdivision and SEPTA'sWest Trenton Line before it becomes paralleled with frontage roads on each side as it reaches an interchange connecting to Highland Avenue and Old Lincoln Highway, heading near homes and businesses. The route curves to the east-northeast and runs through residential areas, crossing into the borough ofLanghorne Manor, where it has a northbound exit and southbound entrance at Hulmeville Avenue. The freeway heads back into Middletown Township again and comes to an interchange providing a connection toPA 413 via South Bellevue and East Gillam avenues. Past this interchange, the frontage roads end and US 1 heads northeast through wooded areas with nearby development, reaching a partial cloverleaf interchange atPA 213. The route passes near residential and commercial development before it heads through wooded areas and bends to the east-northeast, crossingMill Creek. The freeway passes over the West Trenton Line and Trenton Subdivision south ofWoodbourne station on the West Trenton Line before it comes to a bridge over Norfolk Southern Railway'sMorrisville Line and reaches a cloverleaf interchange withI-295.[2][7]

Past the I-295 interchange, US 1 heads east and runs to the north of an industrial park. The route becomes the border betweenLower Makefield Township to the north andFalls Township to the south and comes to a diamond interchange with Oxford Valley Road, which heads south to provide access to theOxford Valley Mall and theSesame Place Philadelphia amusement park. From here, the freeway fully enters Falls Township and runs between woodland to the north and industrial areas to the south, continuing to an interchange with Stony Hill Road and the northern terminus of US 1 Bus. north of the community ofFairless Hills. A short distance later, US 1 comes to a partial cloverleaf interchange with the northern terminus of the US 13 freeway and Pine Grove Road, where the ramp from southbound US 1 to US 1 Bus. splits from the freeway and also acts as acollector–distributor road for the US 13 interchange. Following this interchange, the route reaches a northbound exit and southbound entrance with the southern terminus ofPA 32. The ramp from southbound PA 32 merges into the collector–distributor road for the US 13 and US 1 Bus. interchanges. At this point, the freeway curves to the northeast and runs through wooded areas with nearby residential and commercial development, entering the borough ofMorrisville. Here, the route comes to a bridge over theDelaware Canal andConrail Shared Assets Operations (CSAO)'s Penn Warner Lead railroad line before it comes to an interchange with Pennsylvania Avenue that provides access to Morrisville. Past this interchange, US 1 comes to a southbound toll plaza before it passes over the CSAO line and theDelaware River on theTrenton–Morrisville Toll Bridge, where it leaves Pennsylvania forNew Jersey and heads into the city ofTrenton.[2][7]

In Chester County, before the US 1 expressway was built there, US 1 continued up the Baltimore Pike (which now has a dead-end section in Nottingham where northbound US 1 veers away from the Baltimore Pike alignment onto the expressway). In Oxford, US 1 northbound ran on South 3rd Street, then turned right on Market Street (PA 472) (North 3rd Street is the beginning ofPA 10), then very quickly turned left onto Lincoln Street, and, after leaving Oxford, the road ran byLincoln University. Approaching Avondale, the Baltimore Pike traffic bent southeast along Pennsylvania Avenue (PA 41), then the Baltimore Pike split off after Avondale. In the town of Kennett Square, northbound US 1 ran along Cypress Street while southbound US 1 ran along State Street, and those streets were marked east to west, not north to south. After Kennett Square, the US 1 expressway ends and its traffic merges onto the Baltimore Pike.
Except for the southernmost part of the Baltimore Pike at Nottingham, the Chester County part of old US 1 is still driveable. There is the deadend mentioned above; also, a small part of the Baltimore Pike is permanently blocked by theHerr's snack company property.
BetweenPhiladelphia andTrenton, US 1 is a part of theLincoln Highway, a cross-countryauto trail that ran fromSan Francisco east toNew York City. It was also a part of theByberry and Bensalem Turnpike betweenOakford (Neshaminy Creek) and Philadelphia.
From theLancaster Turnpike, where the Lincoln Highway headed west alongUS 30, the Lincoln Highway originally headed east alongMarket Street to Penn Square aroundPhiladelphia City Hall, where it turned north ontoBroad Street. (Prior to the building of Roosevelt Boulevard, the main road followed Frankford Avenue to Bustleton Avenue fromCenter City.)
A bypass was added around Center City (in addition to the route through Center City) in 1924, using Hunting Park,Ridge, and City avenues.[8][9] This alignment is now used by US 1, except that Hunting Park and Ridge avenues are now bypassed by the Roosevelt and Schuylkill expressways.
From Broad Street, the Lincoln Highway then headed north on the Roosevelt Boulevard. By 1914, the Roosevelt Boulevard was completed to Rhawn Street, and the Lincoln Highway turned off Roosevelt Boulevard there to reach Bustleton Avenue. The old alignment splits from Bustleton Avenue at Haldeman Avenue and then follows Roosevelt Boulevard. (A short piece of Old Bustleton Avenue southwest of Welsh Road was used, crossingPennypack Creek east of the current bridge.[9])
A 1920 extension took the boulevard to Welsh Road, allowing traffic to turn off Bustleton Avenue there (that route is stillPA 532), and a 1920s extension took it to the intersection with Old Lincoln Highway just north of thePoquessing Creek bridge. North of there, the present US 1 was completed in 1933 to the south end of the 1923 Langhorne bypass and in 1938 to Bellevue Avenue (PA 413) in downtown Langhorne.[9]
From near Hornig Road inNortheast Philadelphia, the old alignment heads through woods, closed to traffic, paralleling powerlines, after which it was upgraded on the spot to become Roosevelt Boulevard. The original route is then gated at an 1805 stone bridge across Poquessing Creek at the Philadelphia city line, just before crossing Roosevelt Boulevard. After crossing Street Road (PA 132), the Old Lincoln Highway then becomes one-way southbound past the Bristol Road intersection and crosses the Neshaminy Creek. (This bridge itself was built in 1921 to replace acovered bridge just to the west.[9])
The present route of Lincoln Highway andUS 1 Bus. was built in 1923,[9] bypassingLanghorne to the south and avoiding two railroad crossings. This crosses under the US 1 freeway just south of the railroad, where the older route had crossed the railroad. From Oakford, the Old Lincoln Highway heads northeast, no longer crossingSEPTA'sWest Trenton Line, as the US 1freeway crosses just to the east. It then headed onto Maple Avenue (PA 213) to pass through Langhorne. Past Langhorne, the original route used what is presently known as Lincoln Highway (US 1 Bus.).
At Fallsington, the original road crossed thePennsylvania Railroad'sTrenton Cutoff on a bridge just east of the present bridge, built on areverse curve to shorten the span. It used Trenton Road and Main Street from the bridge to the intersection with Woolston, where Main Street is now cut. In 1917, an underpass under the railroad was built to the west on Woolston Drive; this became the main route by 1924.[9][10]
It then headed towardMorrisville, where it first crossed theDelaware River theCalhoun Street Bridge, running along Trenton Avenue toFallsington. In 1920, it was moved to theLower Trenton Bridge, passing through downtown Morrisville.
On November 21, 1988, an act of thePennsylvania General Assembly designated the portion of US 1 in Bucks County between the Pennsylvania Turnpike and the New Jersey border as the Martin Luther King Jr. Expressway after civil rights leaderMartin Luther King Jr.[11] On June 14, 2000, the Roosevelt Boulevard portion of US 1 was designated the police officer Daniel Faulkner Memorial Highway in memory ofDaniel Faulkner, an officer of thePhiladelphia Police Department who was murdered byMumia Abu-Jamal in 1981.[12][13] On May 31, 2002, the US 1 freeway in Chester County between the Maryland border and Kennett Square was designated the John H. Ware III Memorial Highway in honor ofJohn H. Ware III, a politician from Oxford that served in thePennsylvania State Senate andU.S. House of Representatives and pushed for the construction of the US 1 freeway in Chester County.[14] On January 19, 2012, the section of US 1 in Bucks County between Philadelphia and the Delaware River was designated the Detective Christopher Jones Memorial Highway after a Middletown Township police officer who was killed while conducting a traffic stop along the highway when two cars collided and hit his police car, which struck him.[15]
On October 29, 2018, work began on a project to reconstruct and widen the portion of US 1 between Old Lincoln Highway and the Rockhill Drive interchange in Bensalem Township. The project widened US 1 to a six-lane road from PA 132 to north of the Pennsylvania Turnpike, upgraded the PA 132 and Pennsylvania Turnpike interchanges, and rebuilt bridges.[16][17] It was completed in December 2022.[18]
On March 22, 2021, construction began to rebuild and widen US 1 between Rockhill Drive in Bensalem Township and north of the US 1 Bus. interchange in Middletown Township, with completion expected in mid-2026.[19] The third and final phase of reconstructing US 1 in Bucks County will take place between north of the US 1 Bus. interchange in Middletown Township and north of the PA 413 interchange in Langhorne.[20]
