Between 8 p.m. and 5 a.m. Wednesday and Thursday nights (Aug. 19-20), all lanes of eastbound Highway 12/18 will be closed and detoured at the Interstate 39/90 interchange in Madison.
The eastbound Beltline ramp to I-39/90 northbound will also be closed during this timeframe. Crews will set girders for the new I-39/90 northbound bridge over eastbound Highway 12/18.
Drivers must use alternate routes, such as I-39/90 southbound to Highway N (Exit 147) and turn around and travel north on the interstate. Access will remain open for the eastbound Highway 12/18 ramp to I-39/90 southbound.
The work operations and highway and ramp closures are weather dependent and subject to change.
