Bridge over Bacon Street on the MBTA Worcester Line at milepost 16.07 in Wellesley. Four tracks wide total; two tracks extant, one track as maintenance path (no track), one un-maintained and overgrown with vegetation (no track).

"The four track, ballasted deck, thru plate girder bridge was one of nineteen bridges erected in 1911 by the Boston and Albany Railroad under the supervision of Francis B. Freeman, Chief Engineer and William F. Steffens, Engineer of Bridges and Structures.

The steel in this structure is now almost totally encased in concrete. As built, it was framed with five parallel riveted plate girders which support encased, closely spaced, rolled section floor beams. The girders are spaced at 13 feet on center. Abutments and bridge seats are constructed of coursed, quarry-faced granite ashlar, but have been extended with concrete. Wing walls on south are granite; on the north, of concrete."- Massachusetts Historical Commission (Peter Stott, MBTA Historic Property Survey Phase II, 03/1988)

I can't think of one off the top of my head. Back in the day, some Trucker Atlases listed heights on truck routes. The NBI sometimes lists dimensions, but I would not take it as Gospel as it does contain the occasional error.

Bacon Street Railroad Bridge, Wellesley, Mass / bridge height for under traffic?
Posted October 28, 2016, by Dave (888biglift [at] gmail [dot] com)

Is there a database of bridge heights?

Thanks in advance for the help.
