Traffic sign replacement begins April 24 in southcentral and southwest Minnesota

MANKATO, Minn. – The replacement of traffic signs which are at the end of their service lives will begin on Monday, April 24 along several highways in southcentral and southwest Minnesota, according to the Minnesota Department of Transportation.

Traffic signs located on various highways in the following counties will be replaced: Blue Earth, Cottonwood, Jackson, Nobles, and Watonwan.   

MnDOT replaces traffic signs on a 15-year cycle to ensure signs are legible for motorists during the day and at night. Over time, traffic signs experience wear and tear, and frequently lose reflectivity in low-light conditions long before indications of their age are obvious in normal conditions.

NTTK, Inc. was awarded the project with a bid of $858,305.75.

There will be little impact to traffic, however, MnDOT reminds motorists to drive with caution and watch for crews working near the roadway. The project is expected to be completed by late August, weather permitting.

Important reminders for motorists regarding work zone safety:

  • Slow down when approaching every work zone
  • Never enter a roadway that has been blocked with barriers or cones
  • Stay alert; watch for workers and slow-moving equipment
  • Obey posted speed limits. Fine for a violation in a work zone is $300
  • Minimize distractions behind the wheel
  • Be patient; expect delays, especially during peak travel times
