This amazing photo archive chronicles the bridge removal and construction, coffer dam building, foundation work, and construction project on the Lower Maumee River Bridge for the Toledo Terminal Railroad by The Foundation Company of Pittsburgh & New York. The Toledo Terminal Railroad was completed in 1903 and at one time owned by most of the major railroads that passed through Toledo forming a loop around the city providing an essential link to all of the industrial factories around the city. The Lower Maumee River Bridge was originally erected in 1902-1903 as a single track truss bridge, but by the Roaring 20s needed a major upgrade to double-track. These images show in reverse order the construction of additional piers, building of coffer dams, massive cranes installed to remove the old trusses, and install new trusses, as well as build the swing span. Along with photos of the control systems, the entire intricate process of removing the original single span and installing the double-track trusses is depicted, as well as the new swing span in operation. The Foundation Co. was founded in 1900 by Remington, Jarrett, and Moran, and grew rapidly in the opening decades of the 20th century, often securing numerous large projects, including the building of several dams on the Ohio River to offset flooding, railroad bridges, and more. It should be noted that the MichiganRailroad project, Bridge Hunter, and several other references list this still existing and operational railroad bridge as having been constructed in 1902-1903 as double-track, but these images clearly show the massive three-year project replacing the original from 1927-1930.
