The main route between Carson Valley and Lake Tahoe could be closed for construction before Memorial Day and after Labor Day under a plan to resurface the Tahoe side of Kingsbury Grade in 18 months or less.
Four miles of roadway will have to be taken down to the ground, a process the Nevada Department of Transportation said could take up to three years using traditional traffic control methods.
“The roadway is falling apart,” Project Manager Pedro Rodriguez told Douglas County commissioners on Thursday. “It needs to be reconstructed.”
How the road will close and when concerned residents and county commissioners on Thursday.
Rodriguez said the state plans to pursue a 12-18-month construction schedule, which would close Kingsbury at the summit to regular traffic coming from Carson Valley.
Only emergency, construction and public transit traffic would be allowed from Carson Valley during that time.
On the other hand, work between Memorial Day and Labor Day would be conducted at night. One lane alternating traffic only would be permitted at night, and one lane would be open in each direction during the day.
Serving an estimated 5,000 vehicles Kingsbury serves commuters who live in Carson Valley and work at Lake Tahoe.
Commissioner Doug Johnson expressed how vital the roadway is as a connection between the South Shore and Carson Valley.
“It’s kind of like closing the Bay Bridge,” Johnson said of the project.
The state initially anticipated spending about $8 million on the project. But it now expects to spend somewhere between $14 million and $15 million.
Natural springs underneath Kingsbury have been bubbling up for some time and deteriorated the road, Rodriquez said. Therefore, water improvements will need to be made throughout the sector, along with a 13-inch, full-depth reconstruction of the roadway.
The proposed project will consist of repaving the existing roadway, addressing safety issues and improving roadway drainage and water runoff.
Other improvements will include the addition of a left-turn lane into Tramway Drive for motorists traveling westbound on Kingsbury, the addition of streetlights near pedestrian crosswalks in a commercial area near Highway 50 and the rehabilitation of certain sidewalks to meet federal requirements.
