Pittsburgh Regional Transit or PRT is the primary provider of bus service in Allegheny County, Pennsylvania. Most PRT routes operate locally around Pittsburgh, but some routes operate outside Pittsburgh. PRT also operates a light rail service within Pittsburgh.
Pittsburgh Regional Transit was renamed from Port Authority of Allegheny County as of June 2nd, 2022. Although buses still wear “Port Authority” branding, all future bus orders will sport new “PRT” liveries.
