HNTB provided design services for the I-190 Cumberland Flyover, an 852-foot-long J-shaped flyover bridge along I-190, which serves as the primary road access to and from O’Hare International Airport.
The new design included a new bridge structure with associated retaining walls over the CTA Blue Line and eastbound I-190. It also improved local access with a new exit ramp system from I-90 to southbound Cumberland Avenue. The flyover bridge also serves as an exit ramp for the Illinois Tollway, so it was designed to support IL-120 loading, along with meeting additional Illinois Tollway structural design criteria.
With improved structures, drainage systems, lighting systems, ITS equipment and signing, the new I-190 Cumberland Flyover provides Chicago travelers with better, easier access to one of the country’s busiest airports.
