Ma & Pa Overpass These abutments supported the York Road plate girder bridge of the defunct Maryland & Pennsylvania railroad. The overpass was rebuilt by the Baltimore & Lehigh railroad in 1900 as an upgrade from a previous narrow gauge track. Reorganized formally on February 12, 1901, the railroad became affectionately known as the "Ma and pa". It covered a circuitous 77 mile route between Baltimore, Maryland and York, Pennsylvania. Railroad service was officially abandoned in June 1958, due to greatly reduced traffic and deteriorating bridges and trackage. The overpass was removed in 1959. Historic Towson, Inc.
