Road construction on US Highway 12 between Elkhorn Road/County Highway P and WIS 20/WIS 67 started in late March and was scheduled to be completed in “late summer.” This project was completed on July 25. Upgraded traffic signal equipment was installed at the US 12 and Elkhorn Road/Cty P intersection. The entire highway was resurfaced, and rumble strips were added to the centerline and the shoulders.

Rumble strips, “known for their auditory and tactile warnings, have proven to be an effective measure in ensuring driver safety. These patterns on the pavement surface alert drivers who have drifted out of their travel lane, whether due to distracted driving or fatigue, providing them with an opportunity to correct their steering. The Federal Highway Administration reports that rumble strips reduce:

Crossover crashes by 40-60 percent when center line rumble strips are installed
Single vehicle run-off-road fatal and injury crashes on rural freeways by nearly 29 percent when edge line rumble strips are installed”

The following was provided by Amy Limones, Walworth County Highway Department Operations Support Assistant:

“CTH-A is a closed to all through traffic. Meaning unless a person lives on it or is going to a business located within the work zone, they are to use alternate routes.

The project began after Memorial Day and has always been scheduled for completion the end of September.

They are trying to keep cars off of CTH-A between North/South CTH-P in order to continue with work now that US12 is reopened. They realize the gas station is within that location and there will be vehicles that need to go through.

At this time, milling continues to be done and I believe they are starting to pave. Work was to be done all day this past Saturday but it was cancelled because of the rain Saturday morning.”
