Starting Wednesday (Sept. 22), the I-39/90 northbound ramp to US 12/18 eastbound (Exit 142B) in Madison will be closed until late October 2021. Crews will reconstruct the off-ramp as part of the ongoing I-39/90 and Beltline interchange project. Motorists must use alternate routes, such as the westbound Beltline to the US 51/Stoughton Road interchange.

Also beginning Wednesday, I-39/90 northbound lanes will shift onto the new alignment – adjacent to the southbound Interstate lanes – through the Beltline interchange. Drivers should watch for new traffic patterns and follow the reduced speed limit of 60 mph in the work zone.

The work operations, ramp closure and traffic shift are weather dependent and subject to change.
