The following interchange ramps along the Madison Beltline (US 12/18) will be closed starting Monday (March 29) until Monday, April 19, 2021 (see attached map).

  • Todd Drive ramp to the eastbound Beltline; and
  • Eastbound Beltline ramp to southbound Fish Hatchery Road. Access will remain open for northbound Fish Hatchery Road.

Motorists must use alternate local routes during these closures.

The ramp closures and work operations are weather dependent and subject to change.

This construction project – scheduled for completion in December 2021 – is improving the Madison Beltline inside median shoulders for use as an additional travel lane during peak traffic periods from east of the Whitney Way exit to the I-39/90 interchange. The Flex Lane is anticipated to open in late 2021 or early 2022.

Information on the Flex Lane project can be found at, including weekly updates about the construction progress and associated traffic impacts.
