WIS 49, WIS 23 to South Street, Green Lake County
We identified several needs along this 7.4 mile segment of WIS 49:
- The pavement is more than 20 years old and is deteriorating.
- The guardrail needs to be replaced.
- Six culverts require repair or replacement.
- The current configurations of the climbing lanes are presenting safety concerns, and the lengths of the tapers at the ends of the climbing lanes are short by today’s standards.
- Improvements are needed to provide pedestrian and bicycle accommodations in selected areas.
We plan to replace the pavement with new asphalt along the highway, and at the intersections, using two pavement replacement processes:
- Cold-in-place recycling (South Street to Forest Ridge Road), which uses a portion of the existing pavement structure. The process is most effective in areas with poor soil conditions.
- Pulverize and relay (Forest Ridge Road to just north of WIS 23), which uses the old pavement for the base prior to applying new asphalt.
Both processes are equal in cost and effectiveness. Other improvements include:
- Replacing the deteriorating guardrails
- Replacing deteriorated culverts and lining others to improve service life
- Lengthening the climbing lane transitions
- Installing new pavement marking and signing
- Improving pedestrian and bicycle accommodations from County V to South Street.
The proposed improvements will provide a smoother ride, improve drainage, and maximize the life of the current pavement structure.
To improve safety along WIS 49, we are also proposing to install center line rumble strips.

Traffic impacts during construction
- WIS 49 will remain open to traffic.
- Motorists can expect to encounter daytime lane closures and flagging operations.
- The driving surface may be gravel at times during the pavement replacement work.
- Finalize design - November 2017
- Construction is currently scheduled for 2019, but could occur as early as 2018.
