Ashland Avenue Viaduct at Pershing Road Improvements

Chicago, Illinois

  • V3 performed Phase II design engineering services for improvements to the intersection of Ashland Avenue and Pershing Road in the City of Chicago. In the existing condition, the viaduct carrying through traffic on Ashland Avenue over Pershing Road had exceeded its service life and could no longer be repaired or rehabilitated. The proposed improvements included the demolition of the existing viaduct along with the full reconstruction of the Ashland Avenue and Pershing Road intersection as an at-grade signalized intersection.

  • In addition to eliminating the merge/diverge conditions on either end of the viaduct, the proposed improvements eliminated vertical clearance and sight distance issues and significantly improved pedestrian accessibility.

  • The improvements also included landscaped medians (with irrigation), lighting improvements, traffic signal modernization/interconnection, on-street parking, combined sewer improvements, watermain relocation, landscape restoration and bus shelter accommodations.

  • The project limits extended approximately one-half mile along Ashland Avenue from 40th Street north to 37th Street and approximately one-quarter of a mile along Pershing Road from Paulina Street to 600 feet east of Ashland Avenue.

  • A preliminary site investigation was prepared for the Ashland Avenue corridor to further investigate the high risk sites adjacent to the planned linear excavations and utility relocations.

  • A comprehensive maintenance of traffic plan was critical to the success of the project given the complexities associated with staging the demolition of the existing viaduct and the heavy volumes of traffic on both roadways.

  • The project was federally funded and processed through IDOT-Local Roads.
