"The Old Colony Railroad was incorporated in March 1844 to link Boston with the town of Plymouth. The line opened between South Boston and Plymouth in November 1845, and to its terminus near the present South Station the following year. In 1854, the railroad merged with the Fall River Railroad, giving the company its most famous connection to New York City: steamers which ran for many years between Fall River and the metropolis. The Old Colony continued to expand, with branch lines and connecting cross-country routes. The Old Colony network became part of the New Haven Railroad system in 1893 with a long-term lease by the larger Connecticut-based road. At its peak around 1900, the Old Colony system consisted of over 600 route miles. The core route, Boston-Plymouth, had seven inbound trains each weekday in 1898. After World War I, passenger service declined, and in 1959, all service was terminated.
The Central Street Bridge, constructed in 1898 by the Berlin Iron Bridge Company, is a single-span, simply supported through plate girder type structure with an open deck. It carries one track over Central Street in Abington. The abutments and wingwalls are granite block, which at one time supported an additional track.
The skew angle is approximately 7 degrees at both abutments. The superstructure consists of two riveted steel plate girders with cross bracing, six riveted steel floorbeams, and fourteen riveted steel stringers. The girders are 87.25 and 89.7 inches deep, 13'-0" apart, and span 60*-0" end to end. The floorbeams are 25.4 inches deep, 8'-6" apart, and span 13'-0". The stringers are 20 inches deep, 6'-0" apart, and span 8'-6" (varying spans at the skewed abutments)."
