LANSING, MI – The Michigan Department of Transportation (MDOT) will open the M-30/US-10 roundabout in Midland County on Monday, June 29th, 2015. Traffic will be open in both directions, bringing the project completion date in ahead of schedule.

“We have a strong team of MDOT staff and contractors who pulled together to complete this project as quickly and safely as possible,” said Brian Atkinson, operations engineer for MDOT’s Mt. Pleasant Transportation Service Center (TSC). “We know this was a significant impact on businesses and residents north of US-10, but we’re looking forward to seeing the roundabout in use and seeing how it impacts safety in the community.”

While the roundabout will open to traffic on June 29,more work will need to be completed. Crews will return for landscaping, light pole installation, and some clean up. That activity will have minimal impact on motorists. The community will be notified in advance of any travel restrictions that may occur.

MDOT Mt. Pleasant TSC Manager William Mayhew said he is looking forward to seeing the safety improvements this roundabout will bring to the area. “We understand there is some confusion and misconceptions about roundabouts. However, studies have shown roundabouts increase safety by reducing high-impact crashes by 35 percent and serious injuries and fatalities by 90 percent. The biggest concern is learning to use them properly so that traffic continues flowing and drivers are more comfortable.”

Mayhew also notes that roundabouts reduce long-term operational and maintenance costs associated with traditional intersections featuring traffic signals. Without the need to power or maintain a traffic signal, roundabouts provide a savings of about $2,000 – $5,000 per year.

MDOT has produced an instructional video featuring proper use for the M-30 roundabout: Local motorists are encouraged to watch the video to familiarize themselves with the new traffic feature.
