Due to the location of the project and high traffic volumes, the work is required to be performed in multiple stages. Other challenges include coordination with multiple adjacent highway contracts, McCormick Place events, Chicago Dept. of Transportation and Chicago Dept. of Water Management.
Construction adds a traffic lane along ramp ES from Northbound 1-55 to Southbound Lake Shore Drive, the removal and complete replacement of ramp EN from Northbound I-55 to Northbound Lake Shore Drive, and the reconstruction and widening of the Northbound I-55 bridge. The gross net length of the project is 1 mile.
