On-Time and On-Budget

The Wells Street Bridge in Chicago reopened to vehicle, pedestrian, train and bike traffic on budget and ahead of schedule in November 2013. The double-leaf bascule bridge crosses the Chicago River, carrying trains of the Chicago Transit Authority on the upper level, and pedestrians and vehicles on the lower level.

WSP’s Role

WSP USA provided construction engineering services on behalf of the Chicago Department of Transportation, working with the agency to extend the life of the nearly 100-year-old structure and preserve its original character.

The construction plan for the structure involved rehabilitation of the bridge trusses with selective replacement and/or repairs; replacing floor beams, gusset connection plates, roadway stringers, and grating; replacing sidewalk support brackets, stringers, panels, railings, and all access walkways; cleaning and painting of structural steel and bridge machinery; repair and/or reconstruction of river walls, abutments, back walls, and river dolphins; rehabilitation and/or replacing electrical and mechanical systems; and rehabilitation of all architectural elements of the bridge houses.
