PA Turnpike 66 begins inNew Stanton at acloverleaf interchange withUS 119, nearInterstate 70 andInterstate 76/Pennsylvania Turnpike. Up to Arona Road, its first interchange, no tolls are collected. The route then meetsPA 136 before reaching the Hempfield Toll Plaza.
NearJeannette, PA Turnpike 66 interchanges withUS 30 andPA 130. North of here, the road meetsPA 66 Business before reaching the northern terminus of the same route 3 miles (4.8 km) further north.
At this point, PA Turnpike 66 becomes PA 66 and the freeway ends at a traffic signal just north. PA 66 then meetsUS 22 at asingle-point urban interchange.

North of the Amos K. Hutchinson Bypass, PA 66 entersSalem Township as Sheridan Road. InDelmont, PA 66 is called Sheridan Road. InWashington Township, PA 66 passes west ofBeaver Run Reservoir.
In the village of Mamont, PA 66 intersectsPennsylvania Route 286. In the village of Poke Run north of PA 286, PA 66 intersects the eastern terminus ofPennsylvania Route 366. Then PA 66 intersectsPennsylvania Route 380, PA 380 west heads for downtownPittsburgh.
South ofOklahoma, PA 66 intersects the southern terminus ofPennsylvania Route 356. In the village of Paulton, PA 66 intersects the southern terminus ofPennsylvania Route 66 Alternate.
PA 66 Alternate goes intoVandergrift and PA 66 goes intoApollo. InOklahoma, PA 66 meets the northern terminus ofPennsylvania Route 819. In downtown Oklahoma, PA 66 turns to the east and crosses theKiskiminetas River.
After crossing theKiskiminetas River, PA 66 entersArmstrong County and begins a concurrency withPennsylvania Route 56 inApollo. As they began their concurrency, PA 56/PA 66 are called Warren Avenue in Apollo. As PA 56/PA 66 enter the boro ofNorth Apollo they parallel the Kiskiminetas River. In the village of North Vandergrift, the concurrency between PA 56 and PA 66 ends when PA 66 intersects PA 66 Alternate and PA 56 and PA 66 ALT begin their own concurrency intoVandergrift.
As PA 66 continues to parallel the Kiskiminetas River, it is called Lincoln Avenue. While paralleling the Kiskiminetas River, PA 66 has snake like curves. InLeechburg, PA 66 becomes Market Street, 3rd Street, and Pershing Avenue. As PA 66 exits Leechburg it does not parallel theKiskiminetas River.
InBethel Township, PA 66 meets the northern terminus of PA 66 Alternate. InFord City, PA 66 becomes Main Street and intersects the northern terminus ofPennsylvania Route 128 at an "Y" intersection.
Southeast ofKittanning, PA 66 begins a concurrency withU.S. Route 422 andPennsylvania Route 28 at an interchange. At the next exit US 422 leaves the concurrency and PA 28/PA 66 continue north at-grade.
InRayburn Township, PA 28/PA 66 intersect the western terminus ofPennsylvania Route 85. PA 28/PA 66 continue towards the northeast without intersecting a route for more than 17 miles (27 km).
InSouth Bethlehem, PA 28/PA 66 become Broad Street and meet the northern terminus ofPennsylvania Route 839. The route then crosses the Redbank Creek into Clarion County after spending 43 miles in Armstrong County.
After crossing the Redbank Creek, PA 28/PA 66 enterClarion County. InNew Bethlehem, the concurrency between PA 28 and PA 66 ends when PA 66 leaves PA 28.
North of PA 28, PA 66 becomes Wood Street and intersects the eastern terminus ofPennsylvania Route 861. InClarion Township, PA 66 begins a concurrency withInterstate 80 at exit 64. Then I-80/PA 66 meetPennsylvania Route 68 at exit 62.
After crossing theClarion River, PA 66 leaves I-80 at exit 60 (trumpet interchange). PA 66 continues north at grade. InPaint Township, PA 66 intersectsU.S. Route 322 as Paint Boulevard. PA 66 continues towards the north paralleling rail road tracks.
InFarmington Township, PA 66 intersectsPennsylvania Route 36.
As PA 66 entersForest County, PA 66 intersects the northern terminus ofPennsylvania Route 899. InJenks Township, PA 66 entersAllegheny National Forest. As PA 66 entersElk County, PA 66 has a 2 miles (3 km) concurrency withPennsylvania Route 948. Northeast of PA 948, PA 66 becomes Kane-Russell City Road. PA 66 entersMcKean County as Fraley Street. InKane, PA 66 ends at a "T" intersection withU.S. Route 6.[3][4]
The original road was designated in 1927.[5]
In 1930, the section from West Virginia to Greensburg was decommissioned in favor of US 119. Following this, in 1935, the northern terminus was relocated to Tioneasta.[5]
Construction on the US 22/PA 66 cloverleaf was completed in 1958.[5]
In 1960, the designation was moved from Courthouse Road to bypass Kittanning on a new alignment.[5]
In 1968, route moved onto I-80 to bypass Clarion and onto its current route between Clarion Junction and Kane. That same year, PA 66 was routed onto its current alignment from US 322 north to its current terminus.[5]
In 1982, the road was widened to four lanes with a median from Ford City to US 422.[5]
From August 1990 to December 1993, the Amos K. Hutchinson Bypass was opened as an extension. It was designated as PA Turnpike 66 and designated as the Amos K. Hutchinson Bypass. It was tolled, and supported cash, as well as a system known as the PTC Credit Card.[5]
From 1999 to 2000, the interchange with US 22 was rebuilt into a SPUI.[5]
From 2000 to 2001, the Kittitang Bypass was opened.[5]
E-ZPass was added to the Amos K. Hutchinson Bypass in October 2006.[6]
In Westmoreland County, part of the road was dangerous in Winter due to ice. This was corrected in 2011 as part of a resurfacing.[5]
In 2016, Exit one was officially named the David B. Sheridan Memorial Interchange.[7]
Tolls along PA 66 were originally paid with toll plazas. At the mainline ones, a staffed full-service lane existed, accepting cash or credit cards. For most exit ramp tolls, exact change was required; however some automatic toll collection machines accepted paper money and gave change. All toll collecting machines gave receipts. On October 27, 2019, all-electronic tolling was implemented along the Amos K. Hutchinson Bypass section of PA 66.[8]
The Amos K. Hutchinson Bypass portion of the route has tolls. Tolls are collected once during travel on the road, either at the mainline toll barrier, or at the exit or entrance point, depending on the possibility of reaching the mainline toll barrier during travel. No toll is charged for travel between exits 0 and 1 or north of exit 12.
The Amos K. Hutchinson Bypass usesall-electronic tolling, with tolls payable bytoll-by-plate (which usesautomatic license plate recognition to take a photo of the vehicle's license plate and mail a bill to the vehicle owner) orE-ZPass. As of 2024[update], the mainline toll barrier between exits 4 and 6 costs passenger vehicles $5.50 using toll-by-plate and $2.90 using E-ZPass. At the northbound exit and southbound entrance at exit 4 and the southbound exit and northbound entrance at exit 6, passenger vehicles are charged $4.70 using toll-by-plate and $1.90 using E-ZPass. The southbound exit and northbound entrance at exits 8 and 9 costs passenger vehicles $3.50 using toll-by-plate and $1.50 using E-ZPass.[9]

| Existed | 1938–present |
Pennsylvania Route 66 Alternate (PA 66 Alt.) is an 11-mile-long (18 km)alternate route throughWestmoreland County andArmstrong County, Pennsylvania.
It leaves its parent route inWashington Township and travels through the center ofOklahoma andVandergrift, while the mainline route bypasses residential neighborhoods along the riverfront.
PA 66 Alt. merges withPA 56 to cross theKiskiminetas River. It becomes a separate route again inParks Township (North Vandergrift), avoiding several riverfront towns as it travels along a hilly, rural stretch, before rejoining mainline PA 66 inBethel Township.
From 1928 to 1938, the segment from North Vandergrift to the northern terminus was designated as PA 566.

Pennsylvania Route 66 Business (PA 66 Bus.) is an 8-mile-long (13 km)business route inWestmoreland County, Pennsylvania, connected two fingers of suburbia located east ofPittsburgh. The highway was signed PA 66 Business after PA 66 was shifted onto a newly created toll road bypass.[12]
The route begins nearly a mile south of the original terminus of PA 66, at a juncture withUS 30 (which loops as a freeway around the city). It is cosigned withUS 119 andPA 819 to the city center, before traveling on its own accord through several suburbanized miles.[12]
The route then becomes more rural, as it provides a free connection to the east-central edge of suburban Pittsburgh atDelmont. The highway is designated by PennDOT SR 0119 between US 30 and Pittsburgh Avenue in Greensburg (along the concurrency with US 119), then is part of SR 0066 north of there.[12]
Major intersections
The entire route is inWestmoreland County.
