The Trans-Canada Highway has been opened east of Field, to the relief of residents and visitors trapped in the Rocky Mountain community since Sunday by a series of avalanches.
Motorists hoping to head west could be stuck until at least Wednesday as crews continue to clear a way through the Kicking Horse Canyon, the only other route out of town.
Mike Boissonneault, the avalanche control manager for the Ministry of Transportation and Infrastructure, said crews have finished blasting away precarious snow, and are trying to get the route clear.
Crews have to haul the snow away instead of pushing it over the edge because a railway track runs below the road, and it's taking time, Mr. Boissonnealt said.
"They're working feverishly to restore all four lanes of traffic," he added.
Jennifer Coffman, owner of the Kicking Horse Lodge in Field, said recent days have been an "adventure," but residents know that avalanches and bad weather come with living in a mountain town.
"We're having a snow party," she said, adding that she hasn't noticed a sense of emergency.
A new avalanche on Tuesday morning further west along the Trans-Canada Highway between Revelstoke and Glacier National Park severed that portion of the route for the second time in recent days, but Mr. Boissonneault expected it cleared again by Tuesday evening.
Mr. Boissonneault said colder, clearer weather diminished the avalanche hazard throughout the day.
Crews can now focus on clearing away the rest of the snow and debris, he said.
