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 6-year Capital Improvement Plan (CIP) identifies construction and resurfacing projects from 2024 to 2029. All County and State projects displayed are subject to change.

The purpose of these projects is to address a deteriorating pavement structure and cross culverts and evaluate/improve safety by addressing substandard intersections, vertical geometry and sight distance along the roadway.

Improvements include reconstructing the roadway to improve vertical profiles, increase sight distances, add turn lanes, widen the paved shoulder and replace deteriorating cross culverts to enhance safety and efficiency of the roadway. Western Ave to STH 60 is was completed in 2026. STH 60 to the south curves is scheduled for 2027.

CTH D Pulverize and Relay (CTH WW to Kettleview Drive south) - ROAD OPEN

The Washington County Highway Department in cooperation with the Wisconsin Department of Transportation pulverized and repaved County Trunk Highway (CTH) D from CTH WW to Kettle View Dr South. This is a 5-mile stretch of road in the Towns of Barton and Wayne. The project began the week of April 28th, 2025. Culvert improvements, new asphalt surface, striping, signs and beam guard were all included in the scope.

Payne & Dolan, Inc. was the prime contractor and performed the pulverizing and paving operations.  Please click the button below to review the project documents.

CTH A Bridge Reconstruction - BRIDGE OPEN

The bridge on CTH A east of CTH M in the Town of Farmington, Structure B-66-944, was structurally deficient and functionally obsolete with a sufficiency rating of 36.1 out of 100 and had a substandard roadway width of 24 feet. The concrete deck had heavy cracking throughout, required repeated deck patching, and had exposed rebar on the curbing and side faces. The steel girders had heavy corrosion near the deck drains and along the top flanges. The abutments and piers had cracking, delamination, and spalling. The heavily rusted metal railing had missing sections of posts and rail. There are large farms in the area that utilize this road with their wide farm equipment. This bridge sees heavy recreational use from kayakers and canoeists as a drop off/pickup location.

The bridge’s deteriorated condition dictated the need for a full replacement. Washington County has constructed a three span, concrete haunched bridge, with concrete abutments and piers supported on piles.  The new profile flattened the crest vertical curve lowering the profile by less than 1 foot. The new bridge will has a 40-ft clear width for vehicles. Approach guardrail was upgraded to current standards. The Riverside Road intersection was relocated to the west allowing the installation of standard guardrail on the approach to the structure.

CTH S - STH 28 to FDL Co line - PROJECT COMPLETE & ROAD OPEN!

The Washington County Highway Department repaved a 1.5-mile stretch of County Trunk Highway (CTH) S from STH 28 north to the Fond Du Lac County line. The project was completed and the road was opened on August 17, 2026.

Washington County is planning roadway improvements along an approximate 2.2-mile section of CTH M from the intersection of CTH NN northerly to Knollwood Road in 2028. The project is located in the Town of Jackson and Town of Trenton. The project will improve the condition of the existing roadway pavement with upgrades to the horizontal and vertical curves from CTH NN to Knollwood Road, roadway cross section (paved shoulders), and improvements to the various intersections, all of which will improve safety for the travelling public. No assessments will be levied for this project.

A Public Information Meeting was held on Tuesday, October 13, 2026 from 5:30 p.m. to 6:30 p.m. at the Trenton Town Hall, 1071 Highway 33E, West Bend, WI 53095. There was a brief presentation followed by a question-and-answer session. Documents related to the meeting as well as a copy of the presentation are available in "Project Documents" below.
