in Upper Darby. The entire turnpike between Philadelphia and Newtown Square became a stone road by 1885. The Philadelphia and West Chester Traction Company established a trolley service along the West Chester Pike between 63rd Street in Philadelphia and Newtown Square in 1895. Steam dummies were first used but electric trolley cars were introduced a year later. The trolley line was extended west to West Chester in 1898. The trolley line followed the south side of the turnpike. Following the construction of 69th Street Terminal in Upper Darby in 1907, the route of the West Chester Pike saw increasing suburban development. In 1918, the West Chester Pike was taken over by the state, with the tolls removed. The West Chester Pike was designated as Legislative Route 133 when the Sproul Road Bill was passed in 1911. In 1927, the West Chester Pike and Market Street in Philadelphia were designated as part of PA 5, which ran along the Lakes-to-Sea Highway. Between downtown West Chester and Paoli Pike, PA 5 had a concurrency with US 122/PA 52 (later US 202) along Gay Street. In 1937, PA 3 was commissioned between US 202/US 322/PA 100 (now US 322 Bus.) in West Chester and US 30 in Philadelphia, replacing the previous PA 5 designation. In Philadelphia, PA 3 was shifted by 1940 to follow Chestnut and Walnut streets east before turning north on 5th and 6th streets to meet US 30 at the approach to the Benjamin Franklin Bridge over the Delaware River. The John F. Kennedy Boulevard section of PA 3 was originally part of Filbert Street. The stretch of land between Market Street and Filbert Street once contained a viaduct carrying several tracks of the Pennsylvania Railroad that led to Broad Street Station. The viaduct provided a physical and social barrier between areas north and south of Market Street that came to be known as the "Chinese Wall." In 1930, the Pennsylvania Railroad opened Suburban Station, with a new bridge over the Schuylkill River and railroad line parallel to the "Chinese Wall" leading to the new station. With the opening of the Suburban Station, the Pennsylvania Railroad planned to close Broad Street Station and demolish the "Chinese Wall", replacing it with a wide street called Pennsylvania Boulevard that would contain several office buildings. However, the Great Depression put these plans on hold and Broad Street Station and the "Chinese Wall" would
