The Significance of the Des Moines River Wagon Bridge
Condensed from a report prepared for HAER in 1995
"This bridge is one of the few remaining large-scale wagon trusses in Iowa. A locally important crossing of a major river, it is one of the few multiple span pin-connected Pratt trusses remaining in the state. One of its four spans is a long-span Pennsylvania through truss, an important sub-type of the Pratt truss.
"The Wagon Bridge is an approximately 703' four-span steel bridge composed, begining at the east end, of a timber stringer approach span of about 160', one approximately 124' pin-connected Pennsylvania through truss, one approximately 200' pin-connected Pratt through truss, and one approximately 96' pin-connected Pratt through truss. The roadway width is 16'-0" and has a timber deck. The substructure consists of concrete-filled steel cylindrical piers with plate or bar diaphragms, and a concrete abutment at the west end. This abutment was originally constructed of stone, and may have been originally covered with concrete.
"The main span of this bridge is one of the oldest and best preserved large wagon trusses in Iowa. The bridge continues to serve as a locally important stream crossing, and also serves as an excellent example of the work of a very prolific and important Iowa bridge company, about which relatively little is known."
This document was prepared as part of the Iowa Historic Bridges Recording Project performed durng the Summer of 1995 by the Historic American Engineering Record (HAER). The project was sponsored by the Iowa Department of Transportation (IDOT). Preliminary research on this bridge was performed by Clayton B. Fraser of Fraserdesign, Loveland, CO.
