Wisconsin Department of Transportation
On Tuesday and Wednesday nights (July 21-22), crews will set girders for the new I-39/90 northbound bridge over westbound US 12/18 in Madison. To accommodate this work, all lanes of westbound US 12/18 will be closed and detoured at the Interstate during the following times:
- 8 p.m. to 5 a.m. Tuesday night (July 21)
- 8 p.m. to 5 a.m. Wednesday night (July 22)
Drivers must use alternate routes, such as County N south to I-39/90 northbound and then exiting at the Beltline interchange (Exit 142 A). Access will remain open for the westbound US 12/18 ramp to I-39/90 northbound.
The work operations and highway closure are weather dependent and subject to change.
