Part of building/structure is in Topsham, Sagadahoc County, ME.
Significance: Only identified example of an unusual double-deck railroad and suspended vehicular bridge in the state, and a fine example of a rivet-connected Baltimore thru truss design. It is one of only four 1890-1928 Baltimore truss bridges identified in a recent state bridge survey. It was built in 1909 to replace an 1880 double-deck bridge, and illustrates the evolution of the truss type into a heavily-built structure capable of supporting increased locomotive weights. It carries a minor branch of the Maine Central, today used for local traffic, and is an alternate route to a larger road bridge downstream for road travel between Brunswick and Topsham.

I assume this bridge is classified as a Baltimore by HAER--I believe that it is rather a subdivided Warren truss, as you can trace the main diagonals without lifting your finger.
Road portion of the bridge was closed April 6, due to an accident(car hit one of the steel support rods). inspected July 11th, and found extensive repairs are necessary. MDOT does not have the funding for repairs. So the road portion closed until further notice. Railroad section is unaffected and remains opened.
