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.
