Avalanche control maybe? Actual avalanches on that stretch are rare.
Yep, Avalanche control, it was much larger than expected and it completely buried a snowshed. The highway apparently reopened between 3 to 4am but I turned back to Revelstoke around 11 and spent the night in the truck.
I make the trip from Calgary to Vernon on a weekly basis, this is winter #2 and to be honest I really don't mind the trip. I carry pillows, blankets, food, shovels, first aid kit, and most of the time my old Stumpjumper as a alternative mode of transportation (and for fun in the warmer months). I get worried about an unplanned Avalanche occurring and all the green truck drivers on the road, seems nearly every trip has a semi incident of some sort. Heading out tomorrow in the "Polar Vortex".
