Officials say the slide at about Mile 5 of the highway, which a city spokesperson attributed to warm temperatures and rainfall, happened shortly before noon.
Driver Donald Kurz says he was on his way to the airport with his wife and 2-year-old daughter when they encountered the avalanche.
“As we’re approaching the corner, I see this massive wall of snow floating like a river down the highway into the Eyak Lake, which is right across the highway,” Kurz said.
Record snowfall in the Southcentral area this winter has caused other cases of snow and ice fall. An April 6 ice fall on the Seward Highway crushed a pickup truck, inflicting severe head and neck injuries on driver 32-year-old Amanda Lawton.
