Alternate route designations - Beloit-Janesville-Rockford

In the event of a major incident along the I-39/90 Beloit-Janesville-Rockford corridor, alternate routes have been identified to provide travelers with a safe and timely alternative to avoid traffic delays, while still allowing emergency vehicle access to the site. 

Depending on the location and direction of the closure, portable changeable message signs will be strategically placed to advise drivers which route to use. Emergency personnel and signs will continue to direct travelers along the alternate route and back onto the interstate beyond the incident. 

State and local agencies in both Wisconsin and Illinois worked in cooperation to identify the most effective alternate routes and establish incident management procedures that notify appropriate emergency agencies and temporarily detour traffic. 

The Beloit-Janesville-Rockford alternate route corridor involves I-39/90 from US 14 in Janesville, Wisconsin, to the I-39/90 interchange north of US 20 Business in Rockford, Illinois. 

Once an incident has been identified, the appropriate state and local agencies will be notified and the WisDOT incident management coordinator will place the message signs at the predetermined locations to detour travelers. Local media outlets will be notified of the freeway closure and the alternate route to be used.
