The newly-constructed roundabout on highway 15 south of Hutchinson is now open to traffic.
McLeod County Engineer John Brunkhorst says the opening of the circular intersection is about a week ahead of schedule and just in time for the McLeod County Fair.
Brunkhorst says crews will continue to work on the project, resurfacing Highway 15 from the airport entrance to Highway 212. That work will be done under traffic. The project is scheduled to be completed by early September.
Construction on the roundabout in Minnetrista on Highway 7 at Hennepin County Road 11 continues.
With the detour, highway officials say motorists traveling Highway 7 can expect to add about 15 minutes to their travel time. That project is expected to be completed by the end of October.
Officials say roundabouts are often used in new or remodeled intersections to lower the incidence of crashes; they show a 39 percent decrease in all crashes and an 89 percent decrease in fatal crashes. And, roundabouts can handle high levels of traffic with less delay than most stop signs or signals. The tight curves slow traffic so entering and exiting are easier and more efficient.
