Wight & Company was selected by the Illinois Department of Transportation to perform Phase II design services for the reconstruction of .66 miles of Willow Road from the Des Plaines River to Culligan Parkway. The reconstruction included three 12-foot lanes in each direction with a variable-width median to meet the existing roadway sections east and west of the project limits. The scope of work comprised of roadway alignment, profile, lighting, entrance and exit ramp design, intersection and traffic signal design, roadway signage, maintenance of traffic, and structural oversight.
The project also consisted of the rehabilitation of bridges, most notably the removal and replacement of the Cook County Forest Preserve Equestrian Bridge over Willow Road. The equestrian bridge is a 156-foot, single-span bridge with a prefabricated truss, abutments on steel H-piles, and MSE walls. The project also included the rehabilitation of Ramp B over the Des Plaines River, consisting of deck replacement, bearing and expansion joint replacement, structural steel repair, and sub-structural concrete repair. Due to the project's Water of the United States, Wetlands, and floodplains, cut and fill computations as well as 404 permitting were required.
