OMEGA was honored to be joined by representatives from IDOT and Knight E/A at the ACEC Illinois Awards Luncheon to receive the Engineering Excellence Honor Award for the IL 59 at I-88 Diverging Diamond Interchange Project.
OMEGA provided construction engineering services for the total reconstruction of IL Route 59 between Aurora Avenue and Ferry Road, while Knight E/A was the design consultant. Work included design and implementation of an innovative Diverging Diamond Interchange at IL 59 and Interstate 88, providing increased capacity and reduced accident potential.
This $97 million project also included pump station removal and replacement, retaining walls, noise walls, traffic signals, lighting, surveillance equipment, utility relocations, sidewalks, a shared use pathway, traffic signal interconnect, ADA ramps, landscaping and removal/replacement of the bridge carrying Illinois Route 59 over I-88 with two new independent bridge structures.
This innovative interchange is the first of its kind in the Chicagoland area.
