MADISON, Wis. — Construction is now underway on a new interchange between U.S. Highway 12/18 and County Highway AB near the Yahara Hills Golf Course east of Madison.
Work on the project began Tuesday and is expected to run through late October 2023, according to the Wisconsin Department of Transportation.
The project includes a new diamond interchange between the highways just east of the current at-grade intersection with Highway AB.
Access to Highway 12/18 between Interstate 39-90 and the new interchange, except for right turns from eastbound Highway 12/18 to Millpond Road, will be eliminated, and drivers will instead need to use new frontage roads.
WisDOT said the improvements are aimed at reducing the number and severity of crashes while also decreasing travel delays and expanding bicycle and pedestrian access.
Highway 12/18 will remain open during construction work.
