Washington County Highway Department Construction & Projects

Washington County road construction is prioritized on the basis of need and roads are built with federal aid if possible with contracts let to the lowest bidder. The Department's long-range road improvement plans are detailed in its 2050 Transportation Network Sustainability Plan. All County and State projects displayed are subject to change.



CTH W Reconstruction - IN PROGRESS

Washington County is reconstructing a 2.9-mile section of CTH W from State Highway 33 to State Highway 175. The project will improve the poor condition of the existing roadway pavement and substandard roadway width. Turn lanes at intersections and upgrades to the vertical curves are have been evaluated and redesigned to improve safety for the traveling public. Construction is currently in progress with substantial completion anticipated in November of 2021. See the press release below for more details and detour information.

CTH H (Schaefer's) Bridge Reconstruction - November 2021 through May 2022

Washington County will be replacing the CTH H bridge over the Milwaukee River, approximately 1 mile east of USH 45 beginning in early November 2021. The project is expected to be completed in May of 2022. The prime contractor for the project will be Pheifer Brothers Construction Co.

The bridge will be closed to all traffic and pedestrians for the duration of the project. The project will involve replacing the narrow and deteriorating bridge structure built in 1950 with a safer and wider bridge. Another significant highlight of this project is the addition of a 12 ft. wide multi-use path along the south side of the bridge. The bridge serves as an important connector for the Ice Age Trail. The path will provide a safe, barrier separated river crossing for hikers within the Kettle Moraine State Forest.  It will also provide an established crossing for snowmobile trail riders in the winter.

Motorists are asked to follow the posted detour route which will utilize USH 45, STH 28, and STH 144. A detour route will also be posted for Ice Age Trail users. The route will follow along STH 28 and the Eisenbahn State Trail. Information about the closure and detour will be posted at various locations along the Trail in the area.

CTH M Reconstruction

Washington County is planning the roadway reconstruction of a 1.5-mile section of CTH M (Wasaukee Rd), from the intersection of Freistadt Rd (CTH F) northerly 1.5 miles and 1 mile of CTH M (Pioneer Road) from Country Aire Drive easterly to Wasaukee Rd. The project is located in the Village of Germantown, Town of Jackson and City of Mequon.

The project will improve the poor condition of the existing roadway pavement with upgrades to the vertical curves, roadway cross section (paved shoulders), and improvements to the Highland Road and CTH F intersections, all of which will improve safety for the travelling public. The project is currently scheduled for construction starting in spring of 2022. No assessments will be levied for this project.

CTH Q & Hillside Roundabout

Washington County is striving to improve safety at the intersection of CTH Q and Hillside Road along the southern border of the Village of Richfield and the county. The intersection has experienced a total of 30 crashes between 2014 and 2018 with 50% of them involving injuries. The intersection is currently under two-way stop-control with stop signs on Hillside Road and traffic free-flowing on CTH Q. The intersection will be converted to a single-lane modern roundabout in effort to address the type of crashes that have been occurring as well as their severity. The project is being funded through the Highway Safety Improvement Program (HSIP) which involves a 90% federal/state and 10% local/municipal funding split. Construction is scheduled for 2023. A public informational meeting (PIM) is being held on October 13, 2021 for the project.
