New Castle Area Transit Authority

New Castle Area Transit Authority is a public transportation service located in Lawrence County, Pennsylvania. It provides inter-city bus and paratransit service to select communities within the county. Because the region is located within the metropolitan (but not the urban) area of Pittsburgh, service is provided to the downtown area.
Connections can no longer be made to Youngstown's Western Reserve Transit Authority. The western end point of the New Castle system is on Route 91, on U.S. 422 at the Country Manor Social Hall at the Ohio/Pennsylvania border , about 3 miles from the easternmost point in the WRTA system (Route 32 Wilson-Struthers, U.S. 422 at Struthers-Liberty Road). The New Castle system formerly served the nearby Lincoln Knolls Plaza and made a direct connection with the WRTA route, but New Castle buses no longer enter Ohio.
