The approximately $60 million span, known as the Navy Pier Flyover, will rise above the ground from the Chicago River to Navy Pier. When completed in 2018, the 16-foot-wide bridge will eliminate close encounters between vehicles and nonmotorized traffic by permanently rerouting one of the most heavily used sections of the lakefront trail away from the lower-level sidewalk along the Lake Shore Drive bridge near Lake Point Tower. Bikers, pedestrians and others will no longer cross Grand Avenue and Illinois Street at street level.
