As part of the I-39/90 Project, construction work is underway on WIS 26/Milton Avenue, between US 14/Humes Road and John Paul Road, in Janesville. From 6 p.m. Monday (March 8) to 6 a.m. Tuesday (March 9), WIS 26 northbound and southbound will be reduced to one lane within these limits. All WIS 26 traffic will shift onto the northbound lanes, and drivers should be alert for crews and equipment in the area.

WIS 26 will remain open to two lanes each way with dedicated turn lanes, and the speed limit will be reduced to 30 mph. Motorists should anticipate backups and delays during peak travel times. Access to local businesses is maintained within the work zone.

More information on the WIS 26 Diverging Diamond Interchange (DDI), including a narrated animation video, can be found at

The WIS 26 ramp to I-39/90 southbound remains closed until late August. Drivers should use alternate routes such as US 14 to the southbound Interstate.

This work and lane restrictions are weather dependent and subject to change. Motorists are reminded to be alert, obey the reduced speed limit and drive with caution in all work zones.
