PROJECT DETAILS
The Touhy Avenue project stretches from west of Elmhurst Road to east of Mt. Prospect Road. Additionally, work will occur on Elmhurst Road between Landmeier Road and Greenleaf Avenue. Mount Prospect Road will be realigned between the entrance to O’Hare International Airport and the Union Pacific railroad crossing. Old Higgins Road will be extended east of Elmhurst Road and will curve north to form a new intersection with Touhy Avenue.
The purpose of this project is to alleviate congestion, enhance safety and accommodate the new tollway construction. This is achieved by elevating Touhy Avenue over the new Tollway I-490 and the Union Pacific railroad tracks, realigning Old Higgins Road and Mt. Prospect Road and enhancing the intersection of Touhy Avenue and Elmhurst Road. These improvements aim to facilitate better traffic flow and connectivity in the region, ultimately contributing to a more efficient and safer transportation network.
