As part of the overall Circle Interchange project, work began in October 2014, to construct a new Ramp NW Flyover connecting the northbound Dan Ryan (I-90/94) to westbound Eisenhower Expressway (I-290) movement. Construction of the flyover was completed in the Fall, 2016.
The construction contract was awarded to James McHugh Construction Company on August 12, 2014, and the scope of the work involved the construction of a new two-lane ramp and bridge that begins just south of Roosevelt Road on northbound I-90/94. The bridge goes over Harrison Street, I-90/94, I-290, and Halsted Street. The flyover ramp ends near Morgan Street on westbound I-290. The length of the improvement is approximately one mile, of which the flyover bridge is approximately 2,000 feet long. The new bridge provides much needed capacity for this critical ramp movement.
The existing ramp for this movement remained open during construction of the flyover bridge. However, the work required the temporary closure of Ramp NE (northbound to eastbound). A detour was implemented for the closed Ramp NE. The detour route had a traffic exit at Roosevelt Road and utilized Jefferson Street, Harrison Street, and Wells Street to connect to eastbound Congress Parkway. Ramp NE remained closed until it was reconstructed during a later phase under a separate contract.
The project also included removal and replacement of some existing retaining walls, construction of new retaining walls, and construction of Noise Abatement Walls on the north side of Ramp NW between Halsted Street and Peoria Street and between Peoria Street and Morgan Street.
Other project work elements included drainage, interstate lighting including underpass lighting and high mast interchange lighting, signing, traffic control and protection, landscaping, urban enhancements and pavement markings.
Construction of Ramp NW Flyover serves as a critical step in improving the Circle Interchange’s overall safety, capacity, and geometric deficiencies.
