I-39/90 Expansion Project

Illinois state line to Madison, Dane and Rock Counties

Manogue Road bridge work over I-39/90, north of Janesville

Posted: April 13, 2017

Starting Wednesday (April 19), crews will replace the Manogue Road bridge over Interstate 39/90, near the Janesville Rest Area in Rock County.

What you need to know:

  • Electronic weekly construction updates for this project will start next Friday (April 21), and continue through the 2017 construction season.
  • The Manogue Road bridge over I-39/90 will be closed to all traffic starting Wednesday (April 19) until late August 2017.
    • Alternate local routes are required during the bridge closure.
  • In early May, the Manogue Road bridge will be removed for approximately four months as crews build the new bridge in the same location.
    • Noise from construction equipment and backup alarms is expected for two or three nights during the bridge removal.
  • I-39/90 will remain open to two lanes in each direction during daytime hours.
    • Periodic nighttime single lane closures will occur between 8 p.m. and 5 a.m. Monday through Friday.
  • This project will improve safety, meet current design standards and lengthen the bridge over I-39/90 to accommodate the Interstate expansion from Beloit to Madison.
  • All lane restrictions, bridge closure and work operations are weather dependent and subject to change.
  • Remember to be alert for crews and equipment in this area, and drive with caution through all work zones.

This project is scheduled to be completed in late August 2017.
