Project Background

Eau Claire County, in partnership with Chippewa County, city of Eau Claire, towns of Union and Wheaton, and the Wisconsin Department of Transportation (WisDOT) is proposing to improve County T from the US 12/WIS 312 interchange to the WIS 29/County T interchange (see Project Location Map).

The proposed improvements would include:

• Expanding County T from two lanes to four lanes, separated by a raised median
• Phase 1: 17^th Avenue to 33^rd Avenue (proposed construction year 2027-2028)
• Phase 2: Alpine Road to 17^th Avenue (proposed construction year 2030-2031)
• Constructing roundabouts at 10^th Avenue, 20^th Avenue, and 30^th Avenue
• Improving and/or reconfiguring other intersections
• Constructing pedestrian and bicycle facilities
• Modifying driveway access (right-in, right-out access only)
• Constructing a box culvert under 30^th Avenue

 Improvements could result in potential relocation of properties, permanent right-of-way acquisition of 57 acres, temporary limited easements involving 3.2 acres and impacts to 0.18 acres of wetlands.
