Torrence Avenue Over Grand Calumet River Bridge
The Torrence Avenue Bridge had deteriorated over time and was closed to traffic in May 2015. Controlled demolition was used to remove it, which allowed the contractor to expedite the construction schedule. STV provided engineering design services for the new structure, a continuous three-span steel girder superstructure with a reinforced concrete deck supported by integral abutments on piles and two new multi-column piers on drilled shafts. Weathering steel was used for the girders to eliminate the need for painting and minimize future maintenance costs. The bridge was widened to two travel lanes in each direction, a sidewalk and a shared-use pathway.
STV, the prime consultant, also provided engineering services for the reconstruction of 430 feet of roadway south of the bridge and 350 feet of roadway north of the bridge, a total distance of 1,300 feet. Modernized street lighting, landscaping and drainage improvements were added to the roadway.
