During the summer construction season, various projects will be scheduled that will impact traffic. For current information on road projects impacting traffic see the announcements page.
Road Projects—Annual Pavement Replacement Program
The Marathon County Highway Department maintains over 600 miles of county highways. The average life of an asphalt roadway is 20 years. Therefore, to maintain a satisfactory level of service for the traveling public, 600 ÷ 20, or 30, miles of roadway need to be replaced annually.
The typical scope of work for the pavement replacement is called full depth reclamation (FDR). With the FDR process, the existing asphalt pavement is ground up in place. The ground asphalt is then used as base course, or foundation, for the new hot mix asphalt. The material is prepared with motor graders and compactors prior to new hot mix asphalt being placed on the roadway. For an in-depth description of the FDR process with illustrations, read “Rebuilding by Reclaiming” from Better Roads Magazine.
In addition to FDR, in 2016, Marathon County began including the use of cold in-place recycling (CIR) on county highways. Similar to the FDR process, a machine grinds the existing roadway into pieces smaller than 2″ across. With CIR, after the pavement is crushed, a foamed asphalt material is added to the material. The mixture is then placed directly into an asphalt paver and relaid on the highway. This material typically requires a minimum of seven days to cure. After it is cured, a final surface of hot mix asphalt is placed over the CIR. Due to the high cost of mobilization, crews may come and perform the CIR work on several segments of highway. Paving crews will follow this process. At times, there can be a month or more between the CIR and final paving stages.
A third option for resurfacing involves placing a layer of asphalt over the top of the existing roadway. This is typically placed on roadways that have a solid structure, but the surface is exhibiting early stages of failure. The overlay improves the ride in the roadway and extends the life of the underlying pavement by preserving it. Overlays vary in thickness, typically from ¾″ to 2″. They cost less and require less time, but have a shorter lifetime.
Additional project information is typically posted 1–2 weeks prior to work beginning in the announcements page. If you would require additional project information, please contact the Highway Department at 715‒261‒1809.

2019 Paving Projects (Anticipated)
CTH N from CTH X to Grand Avenue is anticipated to be under construction in 2019. The City of Wausau is responsible for the roadway from Grand Avenue to Skyline Lane. Marathon County is responsible for the construction from Skyline Lane to CTH X.
Marathon County held a Public Meeting to discuss the project between Skyline Lane and CTH X. The meeting was held on Wednesday, January 24, 2018 from 5:00 to 6:00 PM.
Paving Projects (Delayed)
- CTH K from Decator to CTH A, Village of Maine
- CTH K was anticipated to be included in the 2017 program, but the Highway Department pursued additional funding for the project. It is anticipated the project will be postponed to at least 2020 in order to receive additional federal funding that was awarded for the project.
