"The portion of the Franklin Line extending from Readville to Franklin was originally conceived of as two, short, branch lines; the Walpole Railroad, linking Walpole with Dedham, and the Norfolk County Railroad that ran from Walpole to Franklin. The Walpole Railroad was chartered but never actually built. It was vigorously contested because the populous wanted a local line independent from the larger rail lines planned to Connect Boston with New York City and the upstate Hudson River region. The Norfolk County Railroad, chartered in July, 1847, was promoted by wealthy Blackstone millowner Welcome Farnum (1796-1874). The line was opened for service from Boston to Blackstone on 16 May 1849. Farnum's plan was to extend the line through to the Hudson River in order to bring coal form Pennsylvania mines into New England. Farnum had the proposed route surveyed as far as the Hudson River at his own expense, and in 1853, the line was extended as far west as Southbridge, Massachusetts. Farnum's failure during the Panic of 1857 spelled the end of his involvement with the railroad, but the line was completed to Fishkill Landing on the Hudson in 1881. The Norfolk County Railroad went through several reorganizations, consolidations, and name changes between 1858 and 1869 when the line became part of the New York and New England Railroad. In 1898 the New York and New England became the last major acquisition to come under direct control of the New York New Haven and Hartford Railroad.
The bridge, consisting of two independent sets of stringer girders with lateral and sway bracing and an open deck, was fabricated in 1904 by the King Bridge Company of Cleaveland, Ohio. It is one of only two documented examples of the company's work on the MBTA-controlled rail lines. The bridge appears to survive unaltered and is a representative example of an immensely popular deck plate girder type favored because of its rigidity, ease of construction and installation, and economy."
