MADISON, Wis. — Beginning Aug. 9, the two Interstate-39/90 and US 12/18 interchange loop ramps in Madison will see closures spanning several months.

A traffic advisory from the Wisconsin Department of Transportation on Monday said the following ramps will be closed until mid-November:

  • the I-39/90 southbound exit loop ramp at Exit 142B to eastbound US 12/18.
  • the westbound US 12/18 loop ramp at Exit 267A to I-39/90 southbound.

Drivers will be required to use alternative routes, such as the Beltline and US 51/Stoughton Road interchange. Drivers should also be mindful of lane shifts and follow the reduced speed limit of 60 mph.

The ramp closures and construction are subject to change. For more information on the interchange project, click here.
