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.



Chip Sealing during week of June 21st

Washington County will be chip sealing 19 miles of county highways during the week of June 21, 2021. Chip sealing involves the application of a layer of oil emulsion (a tar-like substance) followed by a layer of small aggregate (chips), compaction and sweeping. Loose gravel will be on the roadways until full compaction occurs. Please drive slowly on freshly treated roads until full compaction is reached.

Traffic on project roads will be open to a single lane of travel during application and will be controlled with the use of flaggers. Travelers and property owners along project roads should exercise patience and expect delays. Use of alternate routes is strongly encouraged whenever possible.

Please see the press release below for a list and map displaying project roads.

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.

Goldendale Rd (formerly CTH Y) and Freistadt Rd Intersection - PROJECT COMPLETE - ROAD OPEN!

Reconstruction of the Goldendale Road and Freistadt Road intersection in the Village of Germantown has been completed and the intersection was opened to regular traffic on 5/21/21. The intersection was reconstructed via a partnership between the Village of Germantown and Washington County. Truck traffic from a nearby industrial park is now able to safely navigate this improved intersection. This completes the collaborative effort between the Village of Germantown and Washington County to transfer the jurisdiction of Goldendale Road (formerly County Trunk Highway Y) to the Village of Germantown.

The project consisted of reconstructing the intersection to address the substandard truck turning movements at the intersection. Improvements included replacement of the existing pavement structure, curb and gutter, increased pavement width to accommodate truck movements, and the installation of storm sewer structures on the west leg. The roadway's typical section now consists of two 12-foot travel lanes and two 6-foot paved shoulders (including curb and gutter pan). Curb and gutter has been constructed around the intersection radii and approaches.

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.

Potential Future Projects

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.
