I-90/94 at I-290 JANE BYRNE INTERCHANGE

CHICAGO, ILLINOIS Construction management services were performed for the construction of a new concrete retaining wall 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. This project consisted of the construction of a new 689’ retaining wall to accommodate planned interchange ramps. Wall construction consisted of the installation of drilled shafts in permanent casing of varying size between 3-1/2’ and 7’ in diameter, the installation of a concrete wall fascia, and construction of an 85’ mechanically stabilized earth retaining wall, all in close proximity to the UIC Student Recreation Center.

This project also includes the relocation of an existing 54” water main to facilitate retaining wall and subsequent ramp construction, the rehabilitation of four existing 54” water mains underneath I-90/94 utilizing carbon fiber lining materials, the abandonment and filling of a 54” water main, and the relocation of a 60” combined sewer utilizing both open cut and augered and jacked methods of construction. Close coordination with the University of Illinois at Chicago and the City of Chicago Department of Water Management was required as part of the contract to facilitate the retaining wall construction and water main and sewer improvements.
