Drivers should anticipate periodic traffic delays as Mt. Rose Highway avalanche control system is replaced
CARSON CITY, Nev. – The Nevada Department of Transportation is advising Mt. Rose Highway
commuters to anticipate upcoming brief traffic delays and stoppages as the avalanche control
system located at the Mt. Rose Highway (State Route 431) summit is replaced.
Beginning in late August through October, Mt. Rose Highway commuters can anticipate
intermittent weekday traffic delays and stoppages near the Mt. Rose Highway summit during
installation of the new system. The periodic traffic delays are anticipated to be less than 30
minutes as a helicopter delivers components for the project.
While NDOT will work to advise drivers in advance of the brief traffic closures via the media and
NVRoads.com web site, some brief traffic stoppages may take place without advance notice as
required by weather and construction schedules.
Since 1992, NDOT has housed a remote-controlled avalanche control system near the summit of
Mt. Rose Highway. When snow build up, NDOT briefly stops traffic away from the area and
activates the system to send shock waves which shake loose snow toward the highway. NDOT
plow operators then remove the snow and safely reopen the road. These controlled releases of
snow can help prevent the unpredictable and potentially dangerous snow slides that could bury
vehicles and motorists on the highway.
This summer and fall, NDOT will install a new avalanche control system to replace the aging
system which has served the highway for decades. The new system will use advanced avalanche
control technologies to further ensure the safety and connectivity of highway travelers.
Also on the Mt. Rose Highway summit, the U.S. Forest Service is repairing restrooms, sidewalks,
curbs and walkways, as well as repaving and striping the parking lot at Mt. Rose Trailhead:
