The completion of the Pittsburgh Railways Interurbans in the early 1900s opened up Bethel Park to accelerated growth and development, making the area an early example of a streetcar suburb. While most of the Pittsburgh area's passenger rail and streetcar services were discontinued in the 1950s and 1960s and further growth was fueled by automobiles, the trolley lines through Bethel Park were kept in service and upgraded to modern light rail standards in the 1980s. All three of Port Authority of Allegheny County's light rail lines run through Bethel Park, with the Blue and Red lines terminating at South Hills Village, and the Silver Line passing through the central business district to its terminus in Library. Park-and-ride lots at South Hills Village, West Library, Lytle, and Washington Junction provide local commuters with an easy trip to Pittsburgh.
