Westbound CSX train Q421 crosses the eastern portion of the historic bridge over the Susquehanna River near Havre de Grace, Maryland.
This bridge was opened for service in 1910, replacing an earlier structure on the same alignment. At 6,109 feet long, it is the longest continuous bridge on the B&O system. A variety of truss styles are evident: the locomotive above is perched atop a Pratt truss; the gons and tanks are on a Pennsylvania deck truss; and a part of the train is transiting through a Pennsylvania through truss.
