Wacker Drive Viaduct

Client

Chicago Department of Transportation

Location

Chicago, Illinois
This $75 million reconstruction of Wacker Drive Viaduct from Monroe Street to Randolph Street in the heart of downtown Chicago east of the Chicago River involved the demolition of the existing viaduct superstructure with partial substructure removal from the north side of Monroe Street to the north edge of Randolph Street on Wacker Drive.

Project Scope

The project included new post-tensioned cast-in-place viaduct superstructure with a latex concrete overlay, re-use of existing caissons, new columns, new grade beams, upper level road work rehabilitation, lower level roadway reconstruction, and Washington Trolley Tunnel and the Chicago Freight Tunnel were filled.

 

Reconstruction was staged so that the upper level storefronts and lower level dock and garage accessibility were maintained.
