State Route 88 and Centerville Lane Intersection to Reopen as Part of Traffic Roundabout Construction

Post Date:05/09/2018 3:54 PM

Following a 10-day construction closure, the Nevada Department of Transportation is scheduled to reopen the intersection of State Route 88 and Centerville Road in Douglas County tonight.CARSON CITY, Nev. – Tonight, the Nevada Department of Transportation is scheduled to complete a temporary intersection closure on State Route 88 at Centerville Lane in Douglas County as part of installation of a traffic roundabout.

The intersection is anticipated to reopen to traffic by 8 p.m. Wednesday, May 9. Construction will continue over the coming week, with a traffic flagger alternating directions of traffic through a single lane closure weekdays from 6 a.m. to 8 p.m. Travel delays of up to 30 minutes are to be anticipated. Major construction is expected to complete May 18, with minor finishing construction taking place in future weeks.

The temporary intersection closure allowed for expedited construction of a compact traffic roundabout at the intersection of SR 88 and Centerville Lane. A smaller version of a modern traffic roundabout, the approximately 80-foot diameter compact roundabout will be slightly smaller in size than the existing SR 88 roundabout at Mahogany Drive. Sloping, raised concrete curbing will make up the roundabout’s 22-foot round middle island. Buses and freight and haul trucks will be able to slowly travel over the raised concrete median to travel through the roundabout. Concrete curbing will also be used to define the outside of the roundabout. The roundabout will not feature landscaping in the middle island.

The posted speed limits on State Route 88 will be reduced to 45 mph approaching the new roundabout, with an advisory speed of 20 mph through the roundabout.

A one-way circular intersection in which traffic flows around a center island without stop signs or signals, the roundabout is being installed to enhance traffic safety. Because traffic enters and exits through right turns only, the occurrence of severe right-angle crashes in roundabouts is substantially less than in many four-way intersections. Roundabouts also have the ability to reduce potentially deadly rear-end crashes which can occur at certain traffic lights. In fact, an Insurance Institute for Highway Safety study found that converting 23 specific intersections from traffic signals to roundabouts reduced injury crashes by 80 percent.

In coming years, NDOT will evaluate the potential of purchasing neighboring land to expand the size of the roundabout.

The approximately $1 million project by contractor Granite Construction Company will enhance traffic safety for the as many as 10,000 drivers who travel near the intersection daily. Additional project information is available at or by dialing (775) 888-7000.
