Daytime single lane closures, followed by a 10-day intersection closure, will begin Monday, April 23 on State Route 88 at Centerville Lane in Douglas County as NDOT installs a traffic roundabout.

  • Daytime single lane closures will take place on SR 88 at Centerville Lane April 23 through 27 from 7 a.m. to 6 p.m., with a pilot car alternating directions of traffic through the intersection.
  • An approximately 10-day closure of the SR 88 and Centerville Lane intersection will then begin Monday, April 30, with nearby detour available via Mottsville Lane and Foothill Road.
  • Following the full intersection closure, drivers will again see weekday daytime single lane closures as construction wraps up directly before the Memorial Day holiday.

Travel delays of up to 30 minutes are to be anticipated during construction.

Project Details

A compact traffic roundabout will be installed at the intersection of SR 88 and Centerville Lane west of Gardnerville.

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. Concrete curbing will also be used to define the outside of the roundabout. The roundabout will not feature landscaping in the middle island.

When complete, 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.

Buses and freight and haul trucks will be able to slowly travel over the raised concrete median to travel through the roundabout.

The approximately $1 million project by contractor Granite Construction Company is aimed at enhancing traffic safety for the as many as 10,000 drivers who travel near the intersection daily. 

Roundabout Information

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.
