Closures planned at US 51/Marathon County U, K interchange in Wausau beginning next week

March 11, 2014

The following closures for the continued reconstruction of the US 51/Marathon County U and K interchange in Wausau are expected to begin Monday, March 17:

  • The eastbound and westbound lanes of County K (Business 51) under the US 51 bridges will be closed until early October 2014. During the closure, traffic will be detoured via County U and Overlook Drive.
  • The on-ramp to southbound US 51 from County K. Crews plan to complete and open a new ramp to southbound US 51 by October 2014.

The schedule is subject to change based on weather conditions and construction status.

The on-ramp to northbound US 51 from County K (Business 51) and the southbound US 51 off-ramp to County K (Business 51) will remain open to traffic. 

The closure of County K (Business 51) is necessary for crews to complete a temporary roadway that will carry US 51 traffic, while the US 51 bridges over County K are completed.

Motorists are reminded to drive with caution as they approach the work zone.
