Construction is scheduled to begin Monday on Highway 14 from Mankato to North Mankato, which has the highest volume of traffic in south-central Minnesota.

Because more than 43,000 vehicles travel the highway on an average day, coupled with lane and ramp closures planned for the project, the Minnesota Department of Transportation (MnDOT) is installing an Intelligent Work Zone system during construction.

MnDOT Traffic Engineer Scott Thompson says the system includes changeable message signs, one on each end of the project, and when traffic starts backing up, the IWZ signs will state that stopped traffic is ahead and traffic should use both lanes.

Thompson says the goal is to provide advanced warning to drivers, preparing them to slow down when unexpected backups are occurring and possibly consider taking an alternate route.

There will be six miles of construction on Highway 14 from Lookout Drive to Highway 22.
