NDOT says it has a backup plan for Mt. Rose avalanche cannons

MT. ROSE, Nev. (KOLO) - NDOT says it expects a key building will pass inspection later this month.

That building houses the avalanche control system above the Mt. Rose highway.

The system has been in operation since 1992. A series of tubes combine oxygen and propane. When ignited, the gas explosion shakes loose any threatening snow that can then be removed from the Mt. Rose Highway. Without the system, uncontrolled avalanches could threaten drivers.

NDOT representative Meg Ragonese tells KOLO 8 News Now, the building and the system are reaching the end of their planned life.

NDOT is planning a new building to house the system, but "we are also evaluating avalanche control methods and operations to keep drivers as safe and connected as possible on the highway," said Ragonese.
