U.S. Route 190 (US 190) is an east–westUnited States Highway inLouisiana andTexas. Segments of US 190 will be upgraded toInterstate 14 (I-14); the first 24.8-mile (39.9 km) segment was opened on January 26, 2017.

The western terminus is at a point where US 190 intersects withI-10, a few miles east ofBakersfield and 20 mi (32 km) west of the town ofIraan, in the middle ofPecos County.

It runs east throughTexas Hill Country speckled with sagebrush, intersecting withState Highway 305 (SH 305), crossing intoSchleicher County, and intersecting withUS 277 inEldorado. US 190 continues east intoMenard County, intersecting State Highway 864, and passing a few miles north ofFort McKavett State Historic Site, enteringMenard and intersecting withUS 83 north a short distance.

Continuing on a northeastward route, US 190 enters McCulloch County and intoBrady. As the closest city to the geographical center of Texas, the city proclaims itself the "True Heart of Texas", "where five major highways meet, making it a major gateway to all regions of the state".^[2] US 190 enters Brady from the south merging andrunning concurrently with northUS 377 andUS 87 through town, intersectingFarm to Market Road 2028 (FM 2028),FM 2309, then splitting with US 87 and US 377, before exiting the city heading east. US 190 goes throughRochelle, entersSan Saba County, throughRichland Springs where it intersectsFM 45, the communities Algerita, and Harkeyville, and intoSan Saba, the birthplace of actorTommy Lee Jones, and an intersection withSH 16. Continuing east, US 190 entersLampasas County, enteringLometa, merging and running concurrently withUS 183 south into the city ofLampasas. Splitting from US 183 and continuing east, US 190 runs throughKempner and into the extreme southern corner ofCoryell County andCopperas Cove, which is located on the southwestern edge ofFort Cavazos. On the east side of Copperas Cove, a concurrency withI-14 begins. US 190 then traverses through part of Fort Cavazos, intoBell County andKilleen. Being directly adjacent to the main cantonment of Fort Cavazos, both Killeen and Copperas Cove depend on the fort and those stationed there.

US 190 next intersects and merges withI-35 throughBelton and entersTemple, where I-14 ends. The highway then merges and runs concurrently withSH 36 south. Continuing east and south, US 190 passes throughRogers and entersMilam County thenCameron and merges withUS 77 south for a distance. A few miles south of Cameron, US 190 merges and runs concurrently withUS 79 north. InHearne, US 190 splits with US 79 and merges to run concurrently withSH 6 south, enteringBrazos County, throughBenchley, and intoBryan, that is considered the heart of theBrazos Valley (Southeast Central Texas), and is part of theBryan-College Station metropolitan area.

US 190 splits with SH 6, turning northeast and merging withSH 21 north, enteringKurten, enteringMadison County also passing throughNorth Zulch, Cottonwood and intoMadisonville, before merging withI-45 south and intoWalker County, then enteringHuntsville, where US 190 splits heading into Eastern Texas.

Continuing east, US 190 entersSan Jacinto County, passing north ofOakhurst andPoint Blank, crossingLake Livingston, enteringPolk County and intoOnalaska. US 190 from the west makes a semi-loop up over Lake Livingston and down toLivingston, intersectingUS 59 andBusiness US 59 (Bus. US 59) and throughAlabama-Coushatta Indian Reservation, enteringTyler County, merging withFM 256 and intoWoodville. East of Woodville, FM 256 splits north and US 190 crosses BA Steinhagen Lake, intoJasper County, intersecting withSH 63 east, and in the center ofJasper intersecting withUS 96. Continuing east, US 190 travels throughHolly Springs and entersNewton County, proceeding intoNewton. In Newton, US 190 turns south through Bon Wier, and then crosses theLouisiana line. In Newton County, US 190 has been designated one of the routes on theGreat Texas Coastal Birding Trail.

US 190 crosses the Sabine River and enters the western portion of Louisiana in swampy bayou terrain three miles (4.8 km) west ofMerryville, Louisiana. Merryville is the location of the old Coushatta Indian village.

From Merryville the highway heads north by northeast to the community of Junction, Louisiana, also referred to as "The Junction".^[3] Junction is whereLouisiana Highway 111 (LA 111) and US 190 intersect and is the site of a roadside marker and the joining of two Indian trails.

From Junction, US 190 heads east toDeRidder, where it runs concurrently withUS 171 south and passes several sites on theNational Register of Historic Places, such as theBeauregard Parish Jail,Beauregard Parish Courthouse, and theDeRidder Commercial Historic District. US 190 runs concurrently with US 171 toRagley, where US 190 parts with US 171 heading east. From Ragley, the two-lane highway heads nearly due east almost parallel toI-10 untilOpelousas. US 190 crosses the northern reach of theAtchafalaya Basin near theMorganza Spillway en route toBaton Rouge. From Baton Rouge, US 190 passes, in placesdivided, throughDenham Springs,Albany,Hammond,Robert,Goodbee,Covington,^[a]Mandeville, before reaching the eastern terminus atSlidell.

The stretch betweenI-12 south of Covington and the intersection withLA 22 at Mandeville is multilane divided withcontrolled access, serving as the primary connector between I-12 and the north end of theLake Pontchartrain Causeway. The highway's eastern terminus is in thebayous near Slidell, at an intersection withUS 90. This junction was once known as the "White Kitchen" after a restaurant that was once located there.^[4][5]

• Atchafalaya Expressway — US 190 in Louisiana
• Earl Rudder Freeway and Central Texas Expressway — US 190 in Texas (part of future I-14)

In the original 1926 plan, US 190 served the purpose of modern-dayI-12 as the road around the north side ofLake Pontchartrain to avoidNew Orleans.^[6] The original western terminus was inBaton Rouge, Louisiana, meetingUS 71 at the Baton Rouge–Port Allen ferry across theMississippi River. US 190 was concurrent withState Route 7 (SR 7, in thepre-1955 Louisiana Highway system) from Baton Rouge toCovington, then SR 34 from Covington toSlidell, Louisiana. The original eastern terminus of US 190 was in Slidell, where it intersectedUS 90/LA 2 (nowUS 11).^[7][8]

In 1935, the route was extended west across the Mississippi River, ending in the western Texas town ofBrady at an intersection withUS 87. The section fromKrotz Springs to the Baton Rouge-Port Allen ferry was a concurrency withUS 71 from 1935 until 1951.^[7]

US 190 was assigned to an additional 150 miles (240 km) across the sparsely populated areas of western Texas south ofSan Angelo in June 1977, taking effect January 1, 1978. US 190 now ran westward to I-10 outside ofIraan, replacing a section ofRanch to Market Road 33 (RM 33) and all of bothFM 1257 andFM 1980.^{[9][10][11][12]}

The original 1926 route followed theJefferson Highway through downtown Baton Rouge, thenLA 426 (Old Hammond Highway) to theAmite River. East of Baton Rouge, significant differences from the current alignment are as follows:LA 1032 through Denham Springs;LA 1027 intoWalker;LA 43 and1040 (Old Baton Rouge Highway) between Albany and Hammond; South Range Road andLA 1067 (Old Covington Highway) between Hammond and theTangipahoa River; andBus. US 190 through Covington.

West of Baton Rouge, the current alignment generally follows the same route since its extension into Texas in 1935. The only major re-routing was between Deridder andElton, where the original route followedLA 26. The portion betweenOberlin and Elton was re-routed in 1937 to followUS 165 toKinder before assuming the current alignment between Deridder and Kinder the following year. Other differences from the current route are as follows:LA 110 through Merryville;LA 3099 into DeRidder;LA 3253,1244,31, and742 between Opelousas andPort Barre; Old U.S. 190 betweenBayou Courtableau andKrotz Springs and betweenEast Krotz Springs, Louisiana Krotz Springs andLottie;LA 77 betweenLivonia andRosedale; andLA 76 between Rosedale and Port Allen.

In 1937, US 190 took over the original route of US 90 from Slidell to theRigolets Bridge (along current US 11 andLA 433) when that highway assumed its current routing intoMississippi. US 190 was given its current eastern terminus at US 90 in the 1940s, following what is nowBus. US 190 (Fremaux Avenue) through Slidell until the 1970s when it was shifted onto Gause Boulevard.

In 1951, US 190 was re-routed alongBus. US 51 (mainlineUS 51 at the time) andLA 22 between Hammond and Mandeville. The new route passed throughPonchatoula andMadisonville and bypassed Covington. The former route through Covington was restored in 1956.

The current US 190 near Krotz Springs is an elevated highway. The road was built as a bypass around the road called Old 190 which continues across theMorganza Spillway to the western edge of Lottie. US 190 crosses theAtchafalaya River on twocantilever bridges known as theKrotz Springs Bridge. It crosses the Mississippi River on the 1940-eraHuey Long Bridge north of Baton Rouge.

The route is now used as an alternate route for I-10, across the Atchafalaya Expressway. Traffic can be diverted alongLA 975 to Krotz Springs, and LA 76 to US 190/LA 1.

Interstate 14 is likely to extend further west and east in central Texas along the US 190 corridor, once adequate funding becomes available. In 2019, RepresentativeBrian Babin (R-TX) introduced legislation in the House of Representatives to extend the I-14 corridor throughOdessa, many parts of which would likely follow the US 190 alignment through parts of central Texas.^[13] Though the bill was referred to the Congressional Subcommittee on Highways and Transit, it is likely that bills featuring a congressional I-14 designation will be proposed in the future, as theFixing America's Surface Transportation Act initially authorized I-14.

The Texas Department of Transportation will upgrade US 190 from a two-lane highway to a four-lanedivided highway from approximately two miles (3.2 km) south ofHeidenheimer, Texas to theBell County-Milam County line. The $77.8 million project will improve driving safety along 7.3 miles of US 190 in central Texas, as newhardened medians will separate each side of traffic. This continues previously completed upgrades along US 190 of two-lane to four-lane highways.^[14] The most recent of these improvements were made to the Heidenheimer area circa 2010.^[15]

US 190 has sixbusiness routes: three in Texas and three in Louisiana.

Business U.S. Highway 190
Location	Copperas Cove, Texas
Length	4.5 mi (7.2 km)
Existed	Jan 29, 2015–present

Business U.S. Highway 190-E is a 4.5 mile (7.2 km) long business route that runs through downtownCopperas Cove.^[16] In 2010, theTexas Department of Transportation was given approval by theAmerican Association of State Highway and Transportation Officials (AASHTO) to move US 190 to a new bypass on the south side of Copperas Cove, leaving the original alignment to be made into a business route. The project had been in the planning phases since the 1980s. After delays due to the construction of what would becomeI-14 to the east of Copperas Cove,^[17] the $46.5 million bypass opened on January 29, 2015, and the original alignment became Business US 190.^[18]

Business US 190's western terminus is located at a signaled intersection with US 190 and Farm to Market Road 2657 (FM 2657). Though signed east–west, the first section of the road runs north-to-northeast toward the city center of Copperas Cove. Turning east after, the road intersectsFM 116, where FM 116 forms a short concurrency with Business US 190 for three blocks. After the concurrency, FM 116 breaks off and continues north towards downtown. Continuing eastward, the road intersects northbound FM 1113 and begins to enter the commercial district of Copperas Cove. The road continues due east past the town's center until it merges with I-14, US 190, andState Highway 9 (SH 9). There is no direct access from eastbound Business US 190 to westbound I-14/US 190 or SH 9.^[19][20]

Business U.S. Highway 190
Location	Killeen, Texas
Length	9.1 mi (14.6 km)
Existed	1991–present

Business U.S. Highway 190-F is a 9.09 mile (14.6 km) long business route that runs through downtown Killeen that follows an old alignment of US 190.^[21] When US 190 was moved off the original route to a southern bypass around both Killeen and the town ofHarker Heights in 1975, the remaining route was initially declared asState Loop 518. In an overhaul of state loop designations throughout Texas, however, the Texas Department of Transportation converted many former U.S. route and state highway alignments into business routes, thus creating Business U.S. Highway 190.

Business US 190 begins at apartial cloverleaf interchange with I-14/US 190 and Hood Road. This interchange is located within the boundaries ofFort Cavazos; the only access to the army base directly from US 190 Business is via Hood Road. The route continues east as Veterans Memorial Boulevard. It intersectsState Highway 195 (Fort Hood Road) as the business route exits Fort Cavazos and enters Killeen city limits. The business route passes through downtown Killeen and crosses FM 439 once passing the commercial district. Continuing eastward, the route passes by Skylar Field Airport and enters Harker Heights, where it intersects both FM 3423 and FM 3219. Approaching US 190, the business route splits: according to the Texas Department of Transportation, the official west-to-east alignment of the route forks to Edwards Drive, while the east-to-west alignment continues on Veterans Memorial Boulevard, though both directions are signed as the business route on the boulevard. At either designation, the roads both lost the designation at their respective I-14/US 190 intersections.^[22][20]

Business U.S. Highway 190
Location	Heidenheimer, Texas
Length	2.5 mi (4.0 km)
Existed	2010–present

Business U.S. Highway 190-J^[23] is a 2.5 mile (4.0 km) long business route that runs through the town of Heidenheimer along an old alignment of US 190.^[15] As US 190 has come to be a major thoroughfare through central Texas, traffic could not handle the two lane road in the primarily residential area. With houses on both sides of the road close to the roadway, a bypass was needed by the mid-2000s. A new four-lane bypass around Heidenheimer looped west around the town, opening in 2010. In October 2010, the AASHTO approved the movement of US 190 to the new bypass. Later in 2010, the Texas Department of Transportation requested AASHTO to also approve the new Business U.S. Highway 190, which had been signed by Texas since US 190's movement. The highway has been subsequently approved and the business route continues to be signed as such.^[24]

Though more aligned north-to-south, the business route is signed west-to-east. It begins at a T-intersection with US 190 westbound. The entrance to Business US 190 is not accessible from the eastbound lanes of US 190 as a grass median divides the highway. Once on the business route, it turns almost immediately to the right and begins a southeasterly track towards the town of Heidenheimer. Another access road from US 190 allows eastbound traffic to turn onto the business route. This connector is signed as 'TO BUSINESS US 190' from the mainline road. Continuing eastward, the road intersects FM 93 at its eastern terminus, also allowing access to US 190. Entering the main residential part of the small town, the eastern terminus of FM 436 intersects Business US 190. Only slightly further east is Business US 190's eastern terminus, where traffic returns to US 190.^[25]

U.S. Highway 190 Business
Location	Baton Rouge, Louisiana
Length	10.8 mi (17.4 km)
Existed	1960–present

U.S. Highway 61/190 Business, also calledFlorida Boulevard and internally designated asU.S. Highway 61-X,^{[citation needed]} is a 10.8 mile (17.4 km) business route that runs along the old alignment of both US 61 and US 190 through downtown Baton Rouge.^[26] Although US 190 is signed as a west-to-east route, US 61/190 Business generally does not have directional signage and changes directions multiple times.

From southeast to northwest, the business route begins at acloverleaf interchange with both US 190, which continues east towardHammond, andUS 61, which continues south towardNew Orleans. Both mainline routes come together to form a concurrency and continue northward along theAirline Highway, while the continuing road from US 190 becomes the business route. The route continues west through a primarily commercial area and pastBaton Rouge Community College before entering downtown Baton Rouge.I-110 northbound has a direct exit to US 61/190 Business (Exit 1C) in downtown Baton Rouge, while southbound motorists must use N. 9th Street (Exit 1G) to connect directly to the business route. US 61/190 Business continues west through downtown until it reaches River Road where it turns right and continues north.

Moving north, the business route passes one block to the left of theLouisiana State Capitol and along theMississippi River before merging onto N. 3rd Street and entering an industrial area. The road curves and becomes Chippewa Street where it now heads east toward I-110. At US 61/190 Business' intersection with Louisiana State Highway 3164, the route turns to the left onto Scenic Highway, now heading north again, running parallel to I-110. The route continues about 2.5 miles (4 km) before reaching its northern terminus at US 61/190. At this point, Scenic Highway is taken over by US 61, now heading north towardsNatchez and US 190 continues westward towardsOpelousas.^[27]

Although US 61/190 Business has been signed as such since 1960, it did not formally get approval from the American Association of State Highway Officials (AASHO) until 1968.^[28]

U.S. Highway 190 Business
Location	Covington, Louisiana
Length	3.31 mi (5.33 km)
Existed	1969–present

U.S. Highway 190 Business, also known as21st Avenue orBoston Street and internally known asU.S. Highway 190-X,^{[citation needed]} is a 3.31 mile (5.33 km) long business route that runs on the old alignment of US 190 throughCovington.^[26]

The road begins at an intersection with US 190 to the west of downtown Covington. The business route continues eastbound into downtown Covington until it reachesLouisiana Highway 21 (LA 21). From here, LA 21 begins to run concurrently with US 190 Business until it returns to US 190 on the east side of Covington. The route was approved by AASHO in June 1969, along with the US 190 rerouting.^[29]

U.S. Highway 190 Business
Location	Slidell, Louisiana
Length	3.94 mi (6.34 km)
Existed	1971–present

U.S. Highway 190 Business, also known asFremaux Avenue and internally known asU.S. Highway 190-Y,^{[citation needed]} is a 3.94 mile (6.34 km) long business route that runs on most of the old alignment of US 190 throughSlidell.^[26] The road begins at the intersection of US 11 (Front Street) and Fremaux Avenue in the 'Olde Towne' neighborhood of Slidell. The business route continues eastbound on Fremaux Avenue until it ends at US 190 (Military Road), where US 190 turns eastbound once again and takes over Fremaux Avenue.

WhenI-10 was constructed in Slidell in the 1960s, the proximity of aweigh station could not allow an exit to be built at then-US 190. Nearby Gause Road (then Louisiana Highway 1092), which paralleled the former US 190, was chosen as the I-10 exit in Slidell. After increased traffic on Gause Road and motorist confusion accessing US 190, the state of Louisiana petitioned AASHO to re-route the highway and create a new business route. At AASHO's June 1971 meeting, this request was approved.^[30] US 190 was permanently routed onto the now widened Gause Boulevard and Military Road while US 190 Business was signed along the former routing by 1975.^[31]

FollowingHurricane Katrina in 2005, the weigh station on I-10 near the US 190 Business overpass was permanently closed and razed. In 2006, theLouisiana Department of Transportation and Development (LaDOTD) began construction on a new interchange at US 190 Business at the request of theSt. Tammany Parish government and the City of Slidell. Extensive traffic backups at the US 190 (Gause Boulevard) interchange and the planning of a new retail center prompted this to be one of many projects to revitalize the area following Hurricane Katrina.^[32] Originally scheduled to open in the spring of 2008, multiple instances of severe weather, the threat ofHurricane Gustav, and signage delays pushed the opening of the interchange to late September 2008.^[33]

Although approved to sign the business route concurrently with US 11 to US 190 in 'Olde Towne' Slidell, the route officially begins at US 11.
