 The US 12/18 westbound ramp to I-39/90 northbound in Madison will be closed starting Wednesday (April 7) until late May 2021. Motorists must use alternate routes such as the signed detour using the Beltline and US 51/Stoughton Road interchange.

The long-term closure will better accommodate traffic operations of the US 12/18 eastbound ramp to the northbound Interstate during this construction stage. The ramp closure and work operations are weather dependent and subject to change.
