Project Updates:
April 23, 2026:
On Monday, May 4, 2026, a shoulder widening project is scheduled to begin on S.D. Highway 10, west of Britton. The contractor will set signs, strip topsoil, and begin shoulder widening operations from Britton, working west three miles. Pipe replacement operations will begin approximately one mile west of Houghton working east to Britton. The contractor will then pave asphalt concrete shoulders from the intersection of S.D. Highway 37 and Highway 10 to Britton.
Travel Impacts:
The shoulder widening construction will involve trucking material to the site. Traffic will be controlled with the use of signs, flaggers, and a pilot car. During daylight hours, speed will be reduced to 45 mph, with stop and go traffic guided by flaggers and a pilot car. Motorists should expect up to a 15-minute delay.
