The Richardson Highway reopened Thursday evening after crews cleared an avalanche that had blocked the only road to Valdez earlier this week.
At 5:30 p.m., the road was open from Mile 12 to Mile 55, which had been blocked off after a 200-foot-long avalanche covered a section of the road, according to the Alaska Department of Transportation and Public Facilities.
Driving conditions Thursday were "very difficult," DOT said in a written statement. "Heavy snow, mixed with rain, is causing ice to form on the road."
A snowstorm had swept through the area, dumping 45 inches of snow on Thompson Pass overnight Wednesday.
In the previous five days, 76 inches of snow — more than 6 feet — had fallen on Thompson Pass, the National Weather Service Alaska Region said in a Facebook post.
Another 2 feet of snow was forecast to dump on the pass through Friday.
