IDOT Circle Interchange Retaining Wall and Water Main/Sewer Improvements
Start/Scheduled Date of Completion:
August 2017 - April 2019
SQN's Role on Project:
As a part of the Jane Byrne interchange, a new concrete retaining wall is being constructed near the UIC recreation building located along the east side of Halsted Street and the East to South ramp from I-290 to I-90/94 south. The new wall will consist of a special design to accommodate the existing adjacent building. Five existing water mains will be rehabilitated/replaced or fiber wrapped since these water mains are running to/from the existing Cermak Pumping Station. Close coordination with the City of Chicago Department of Water Management will be required. One of the water mains will be abandoned and filled within the State’s right of way whereas another water main will be replaced with a 48 inch diameter new water main. Work will also include restoration of one existing tennis court impacted by the water main work for UIC. In addition, a 48 inch combined sewer will be relocated as part of the project. Roadway restoration is also included for an existing driveway. A noise wall mounted on the proposed retaining wall is also included.
