As part of the Phase II reconstruction project for Chicago’s Wacker Drive, more than 1100 cubic yards of concrete was poured on Friday, April 15 to create a new intersection at Wacker and Randolph.

Approximately 125 ready-mix trucks delivered the concrete for nearly 8 hours, according to the City of Chicago Department of Transportation.

The concrete deck is 13 inches thick, the amount of concrete used is equivalent to 18 city blocks of sidewalk, or 2.25 miles.

Crews working on the project removed both Upper and Lower Wacker from Randolph Street to south of Washington Street and installed new columns and forms to support the concrete pour for Upper Wacker.

Concrete Construction will continue to provide regular coverage of the Wacker Drive reconstruction project over the course of construction. Be sure to check our website regularly for project slideshows, movies, editorial features, and more.
