View an article about the construction of this bridge.
This large through truss bridge crosses the Mississippi River at Quincy.
It was built in 1959 as a relocation of the railroad. Previously, the railroad crossed the river on a pair of swing bridges just south of this point.
This new bridge is certainly impressive, but is not very historically notable. It features a large Polygonal Warren Through Truss, which is a modern version of the Camelback Through Truss.

On the west, it is approached by a long string of Warren Deck Trusses. The main span features 12 panels, while the remaining deck trusses feature 10 panels. They are all built as riveted structures.
In addition, a number of deck girder spans approach the bridge as well. It is all set onto concrete substructures.
The author has rated the bridge as minimally significant, due to the age of the bridge.
The photo above is an overview. More photos are coming soon.
