Comstock Bridge Off River - WGN 45-06-04. East abutment. Note the mould-marks showing that the wooden bridge itself was used when the cap was cast, leading to rot. Photo by Joe Nelson, July 7, 2003 July, 7, 2003 - The Comstock Bridge has been disassembled and removed from the river. Its component parts are arrayed in a small meadow at the east end of the bridge site. The trusses are stacked and ready for repair. The separate pieces were lifted by crane, the trusses were laid flat, the west ends now pointing east, the bottom chords to the north, down stream truss on top.        Extensive rot was found at the chord-ends where they were in contact with the abutments. All four of the end-posts will need to be replaced. Lifted by crane, the trusses are laid flat, the west ends now pointing east, the bottom chords to the north, down stream truss on top.
