Construction is expected to begin Monday, April 19 on US 14/Commercial Street, between Walter Road and County KP, in Mazomanie. The project will address deteriorating pavement conditions and substandard pedestrian accommodations. Additional improvements include storm sewer, grading, aggregate, curb and gutter, asphalt pavement, street lighting, sidewalk, and traffic signals at the US 14 and Brodhead Street intersection.

US 14 will remain open to traffic with access maintained to businesses and residential driveways. In June, US 14 will be closed for three weeks as crews install storm sewer pipes under the highway near County KP. During that closure, all traffic will be detoured via WIS 60, US 12 and WIS 78. Pedestrian access will be maintained at the US 14 and Brodhead Street intersection during construction.

Motorists are urged to slow down, eliminate distractions and watch for crews and equipment working near the travel lanes. The $3.2 million project is scheduled to be completed in late September 2021.

Valley Sentinel reached out to Steven Theisen, the WisDOT regional communications manager about what to expect during construction, and alternate routes to take during the closures. Below are his answers.

Valley Sentinel: You stated that full traffic closures won’t be happening until June, but what should commuters expect come April 19?
Steven Theisen: Starting next week, motorists can expect flagging operations on US 14 during the non-peakhours (between 8 a.m. and 3 p.m.) as crews pave temporary asphalt in preparations for the upcoming traffic switch in late April/ early May. At that time, traffic will be shifted into the westbound lanes of US 14 as crews reconstruct eastbound US 14. Although the highway will remain open to traffic, we urge drivers to slow down and watch the road ahead. We also recommend drivers plan ahead and allow extra time if traveling through Mazomanie.

VS: For residents that live in the Arena area and commute east on HWY 14, will they be able to take a local traffic route through Mazomanie on Walter to Hudson to HWY 78? Or will they need to reroute through Spring Green and have to take HWY 60?
ST: We are required to detour through traffic on similar highways to accommodate the type of vehicles (i.e., semi trucks). Therefore, we list the official detour as WIS 78 to Sauk City and WIS 60 back to Spring Green. We recognize that drivers familiar with the area will use local roadways during the three-week closure.
