Construction has been completed on the US 14/County MM interchange and the County M intersection in Dane County.
The $2.6 million project reconstructed the interchange and built roundabouts at the ramp terminals.
Reconstruction was done to the County MM and County M intersection. A roundabout was also added.
The work is the final project in a series of recent improvements to the US 14 Corridor between Madison and Oregon.
According to the Wisconsin Department of Transportation, the improvements include the expansion to four lanes from County MM to WIS 138, reconstruction of the US 14/WIS 138 interchange, highway resurfacing from the Beltline to County MM and the completion of the new Lacy Road interchange in Fitchburg.
