AOM Highway/Bridge Canal Street Plaza Reconstruction
As part of the community and economic revitalization effort around Chicago’s Old Post Office, Canal Street Plaza’s reconstruction required an innovative construction approach thanks to its structure-on-structure design.
Crews also navigated a complex work area. At track level are Amtrak commuter lines. Above is a viaduct structure—owned and maintained by the Chicago Dept. of Transportation—that is attached to the privately owned 100-year-old post office. Cutting through that building and bearing on the viaduct structure is also an Illinois Dept. of Transportation expressway.
