WIS 34/County DB Intersection


WIS 34 and Marathon County DB/Old 51 Intersection, Knowlton, Marathon County


This safety project includes reconstructing the intersection of WIS 34 and County Road DB/Old 51 in the town of Knowlton, in Marathon county. The existing intersection has experienced a significant amount of angle crashes with severe injuries, which may be attributed to the existing horizontal curve on the western approach and the substandard intersection skew angle of 61 degrees.

WisDOT will be moving forward with a roundabout design as the proposed intersection improvement type.

Traffic impacts

Construction will likely require staged construction and may consider closing Old 51 during construction.
