Starting on the week of July 5th, 2022, US Route 67 (Piasa Street) will be closed from 20th Street/College Avenue south to 3rd Street. The intersection at 10th Street and US Route 67 (Piasa Street) will remain open to facilitate traffic flow in and out of Tony’s Restaurant. Access to the Lovejoy Banquet Center will also be maintained, with additional information on access to their parking lot being released as the work progresses toward their property. All other traffic on US Route 67 (Piasa Street) will be prohibited during this time. Posted detour routes will be in place starting on July 5th. This closure will last roughly one month to allow for sanitary sewer and water main installation work to be completed.

Background:

Work kicked off in February 2021 and will continue to progress until 2023. Work includes over six miles of sanitary sewer main is being installed in the Turner Tract, Shields Valley and Piasa Valley areas of Alton. When Illinois American Water acquired the Alton Regional Wastewater system the company made a commitment to address requirements set forth by the Illinois Environmental Protection Agency to remedy combined sewer overflows.

  • The projects in Turner Tract and Shields Valley address 1.69 miles of sanitary sewer main.
  • The work in Piasa Valley began in the spring of 2021.
    • This project includes almost five miles of sanitary sewer main.
    • Work is expected to continue for over two years.
      • This does not mean work will occur in one area for 24 months, but rather, projects will continue to progress throughout neighborhoods during that time period. Signs will be placed ahead of construction to notify customers of upcoming closures.

Safety:

These closures are necessary for investments to the wastewater system to be completed in a safe manner. At Illinois American Water our team and our contractors work as quickly as possible to minimize inconvenience to our customers. We do our best to minimize the length of construction, but our #1 priority is safety. At times, road and sidewalk closures may be extended to support our commitment to safety.
