Pittsburgh Regional Transit
public transit agency in Pennsylvania, USA
The Port Authority of Allegheny County, doing business as Pittsburgh Regional Transit (PRT), is the public transit agency serving Allegheny County, Pennsylvania, including the city of Pittsburgh, with limited service to adjacent counties in the Greater Pittsburgh region.
PRT is the second-largest public transit agency in Pennsylvania and, as of 2022, was the 20th-largest in the United States. It operates a system of bus, light rail, and incline services. The agency was established in 1956 and began transit operations in 1964. In 1977, it opened the South Busway, one of the earliest bus rapid transit corridors in the United States; the network has since expanded to include the East and West busways, which remain a core part of the system. The agency also operates the Wabash Tunnel, 54 park-and-ride facilities, and more than 80 bridges. In 2025, the system recorded 38,452,000 passenger trips.
The agency adopted the Pittsburgh Regional Transit name for public use in 2022 while retaining its legal name. It is constituted as a port authority under Pennsylvania law and is funded by federal, state, and local sources. Governance is provided by a board of directors appointed by Allegheny County, the Pennsylvania General Assembly, and the Governor of Pennsylvania.

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
