MADISON, Wis. — Traffic will begin flowing in a new, safer, and smoother way on Madison’s east side Friday.

WisDOT, Dane County, the City of Madison, and the Ho-Chunk Nation joined prime contractor R.G. Huston to celebrate the grand opening of the US 12/18 and Highway AB interchange.

The project, which began with design in 2020 and construction in 2022, replaced the County AB bridge over Highway 12/18, added roundabouts at interchange ramps, and frontage roads connecting Millpond Road and Long Drive.

“This reconstruction project exemplifies collaboration at all levels of government to fix major safety concerns at this intersection,” WisDOT Secretary Craig Thompson said during a press conference Thursday afternoon.

Finishing work will continue into the fall.  Final completion is set for November.
