. It leaves its parent route in Parks Township (North Vandergrift), avoiding several riverfront towns as it travels along a hilly, rural stretch, before rejoining mainline PA 66 in Bethel Township
.
, connected two fingers of suburbia located east of Pittsburgh. The highway was created when a mainline Route 66 was shifted onto a toll bypass. The route begins nearly a mile south of the original terminus of PA 66, at a juncture with U.S. Route 30
(which loops as a freeway around the city). It is cosigned with Pennsylvania Route 819
to the city center, before travelling on its own accord through several suburbanized miles. The route then becomes more rural, as it provides a free connection to the north-central edge of suburban Pittsburgh at Delmont

Toll structure
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 between exits 12 and 14. Tolls are paid either by cash or E-Z Pass. At the mainline toll barrier, a manned full service lane exists. For most exit ramp tolls, exact coins are required; however some automatic toll collection machines accept paper money and give change. All toll collecting machines give receipts.Usage by trucks
The highway was built primarily to eliminate the need for trucks traveling to northwestern Pennsylvania via U.S. Route 119 and PA 66 from having to travel through downtown Greensburg. When the highway first opened, many trucks avoided the bypass due to the toll along the turnpike. However, turn restrictions in Downtown Greensburg forced many trucks to use the bypass.Westmoreland County
