  • Real estate acquisition: 2022
  • Construction: 2023​

Traffic Impacts

Construction is anticipated to occur in three primary stages. Two of the three will result in the closure of WIS 35 to through traffic. Through traffic will be detoured via Lagrandeur Road, Lemire Street, SMC Drive and Laser Drive. Motorists also can expect to encounter single-lane and shoulder closures with flagging operations as the project is completed.

Access will be maintained for residents and businesses located within the project limits during construction. However, there will be days where access will be restricted because of water main, sanitary sewer and concrete work. These will be coordinated with affected properties in advance.
