Highway 88 closing for roundabout work
April 18, 2018
Work on a roundabout at Centerville and Highway 88 will begin 7 a.m. Monday, snarling one of the main routes Gardnerville Ranchos residents use to commute north.
A pilot car will guide motorists through the intersection next week through 6 p.m. Then the state plans to close the intersection for 10 days starting April 30 while Granite Construction builds the $1.125 million compact roundabout.
Following the full intersection closure, drivers will again see weekday daytime single lane closures until major construction wraps up just before the Memorial Day holiday, state transportation spokeswoman Meg Ragonese said on Wednesday.
Travel delays of up to 30 minutes are to be anticipated. Minor finishing elements of construction such as light pole installation will take place in future months.
The intersection was the most dangerous in Douglas County during 2017, with three deaths. The roundabout is designed to slow traffic down and help people get safely across Highway 88.
Motorists traveling from the Gardnerville Ranchos will be able to use Centerville Lane to Waterloo, if they don't mind the bumpy ride to get to Highway 88.

A smaller version of a modern traffic roundabout, the approximately 80-foot diameter compact roundabout will be slightly smaller in size than the existing roundabout at County Road. 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 drive 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 part due to limited available space in the middle island.
When completed, 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.
