Over the next five months, travelers on an 11 mile stretch of Highway 16 can expect delays.
On Monday, a $7.7 million construction project gets underway.
Crews will begin resurfacing the road, improving medians, pipes, and replacing guardrails on the stretch between Neck Yoke Road near Spring Creek.
Traffic will be reduced to one lane and a speed limit of 45 miles per hour.
Milling will begin in the westbound lanes followed by the eastbound lanes.
No work will be done that impedes traffic from July 27 through August 11 during the Sturgis Motorcycle Rally period.
The project is scheduled to be completed in early October.
