US Route 30 - US Route 45 to IL Route 43

Illinois Department of Transportation - District 1

This project for IDOT District 1 includes the bituminous reconstruction of U.S. Route 30 from US Route 45 to IL Route 43. U.S. Route 30 was designed to be widened to provide 2–12 foot lanes in each direction plus a 22 foot wide landscaped median. Left turn lanes will be provided at most of the side streets. The existing bridge crossing Hickory Creek will be widened on both sides to provide the proposed section and an additional future bike path. A bituminous bike path will be constructed along the north side of U.S. Route 30 throughout much of the project based on local agency support.

At the intersection with Harlem Avenue (IL 43), dual left turn lanes and single right turn lanes will be provided on all four legs. Harlem Avenue will be widened to provide 2–12 foot lanes in each direction with a 30 foot barrier median.

Traffic signals were designed at the intersections of U.S. Route 30 with Pfeiffer Road, 80th Avenue, Frankfort Square Road/Hunter Woods Drive, and Harlem Avenue. A new traffic signal interconnect is also included in the project, and intersection lighting will be installed at the intersection of U.S. Route 30 and Harlem Avenue.

A new enclosed drainage system was designed throughout the project. The existing dual 10’ X 5’ box culvert at the west end of the project will be extended over 1,000’ to the east and cross under U.S. Route 30. Three other major box culverts were also designed as part of the project.

The roadway widening and reconstruction included major profile and alignment modifications at various locations throughout the project. These changes were to improve horizontal geometry and safety, as well as to bring the roadway profile out of the 100 floodplain at the west end of the project. The design required compensatory storage to be provided adjacent to the roadway right-of-way for the floodplain fill resulting from the roadway widening. The above items also required substantial right-of-way acquisition, which Civiltech is coordinating with the Department.
