Motorists on I-43 and WIS 81 in Beloit heading toward Janesville via I-39/90 northbound must use alternate routes starting Sunday night (July 18). The I-43/WIS 81 ramp to I-39/90 northbound will be closed from Sunday night until early August as crews pave concrete connections for the new Diverging Diamond Interchange at I-39/90 and WIS 81. The signed detour route will follow I-43 to Hart Road then Shopiere Road to I-39/90 northbound.
Drivers are urged to plan ahead, use alternate routes, and allow extra time to reach their destination. The ramp closure is weather dependent and subject to change.
Information on the I-39/90 and WIS 81 Diverging Diamond Interchange can be found at projects.511wi.gov/i-39-90/ddi/wis81/.
