Fast work allows Kingsbury Grade to reopen Wednesday (updated)
UPDATE: 5:45 p.m. WEDNESDAY:
On Wednesday, Douglas County residents learned Kingsbury Grade had reopened because the signs at the top of Daggett Summit had disappeared.
Work on the main link between Carson Valley and Lake Tahoe was completed, the state announced via Twitter at 4:50 p.m., although motorists were already using the route.
Replacement of an eroded drainage pipe was completed by contractors working on Kingsbury Grade, and paving began on Tuesday, according to the Nevada Department of Transportation.
A sinkhole where the drainage pipe crosses the highway developed last month, prompting the state to close the highway on Jan. 3. Workers replaced the pipe and patched the road, opening it three days later on Jan. 6.
On Tuesday, NDOT indicated it could take several days to repair the road (which was open on the Tahoe side).
However, the state was able to finish work Wednesday “in the nick of time,” it reported on Facebook, considering incoming wet storms this week.
The original story from Wednesday morning is below.
MINDEN, Nev. — Work on Kingsbury Grade is estimated to take a few weeks, according to the Nevada Department of Transportation.
Crews had to clear 7 feet of snow last week so they could start excavating a drainage pipe that undermined the highway.
“They then worked through the weekend, excavating roughly 30 feet down to remove and replace the aging pipe,” Nevada Department of Transportation spokeswoman Meg Ragonese said Monday. “Some of the next steps will include rebuilding and replacing the roadway above the drainage pipe. Crews will be working as quickly and efficiently as possible to repair this section of Kingsbury Grade, but because some elements of the repair work are weather and temperature sensitive, there is no definite date set for reopening.”
A sinkhole where the drainage pipe crosses the highway developed last month, prompting the state to close the highway on Jan. 3.
Workers replaced the pipe and patched the road, opening it three days later on Jan. 6.
However, heavy rain on Jan. 8 eroded around the patch and the state closed the main route between Carson Valley and Lake Tahoe.
In 2014, NDOT reconstructed a different section of Kingsbury Grade, making improvements to roadway surface, drainage, curb and gutter and more.
The current closure area is east of the reconstructed roadway, and not in the same area that was reconstructed.
The state already has scheduled a project to invest approximately $5 million to enhance roadway drainage and erosion control on this lower section of Kingsbury Grade in 2019. When open, this section of road is traveled by approximately 5,600 vehicles daily.
Kingsbury is open on the Lake Tahoe side from U.S. 50 to Tramway.
