Overview

Client: Chicago Department of Transportation

Description

The City of Chicago Department of Transportation reconstructed the Wacker Drive Viaduct from Randolph to Congress. The deteriorated viaduct structure built in the 1950s was fully replaced, lifting the vertical clearance by more than one foot. New lighting provides improved visibility and new ventilation equipment is providing improved air quality. The service drives and through lanes were separated, alleviating congestion and expediting traffic. Utilities were relocated throughout the viaduct and major adjacent bridges were rehabilitated.
