CHICAGO - The Illinois Department of Transportation (IDOT) today joined CenterPoint Properties, Will County and City of Joliet officials to mark the start of construction of the Houbolt Road Extension, a public-private partnership that will improve safety and traffic flow along the critical Interstate 80 corridor, while expanding job growth and economic opportunity. The project includes a 1.5-mile extension of Houbolt Road, a rebuilt interchange with I-80 and a new bridge connecting to the country's largest inland port. By leveraging an IDOT investment of $32 million to accomplish an overall improvement of nearly $200 million, this project furthers Governor JB Pritzker's mission to overhaul one of the state's key travel and freight corridors.
