COLORADO REPLACES BRIDGES QUICKLY

This article profiles a project performed by the Colorado Department of Transportation (CDOT) involving the replacement of two 70-year old metal truss bridges on U.S. 34 in an area where construction detours would have displaced 200 trees, encroached upon wetland areas, and impacted tourists as well as commuters for several months. Instead, CDOT opted for a plan which the replacement of the bridges over a 10-day period and a 2-mile closure on the highway. The project involved the off-site construction of a large portion of each bridge prior to the closure. Once the bridges were closed, the bridge sections were delivered and put into place. The article details the bridge replacement process and the difficulties encountered. The two metal truss bridges were replaced with concrete box girder bridges that are substantially longer and wider than the old bridges. Along with a new roadway alignment, the project resulted in a safer traveling environment for motorists.
