Two vehicles collided in Midtown Anchorage on Saturday afternoon and one struck a pedestrian, a police spokesman said.
That pedestrian, a man, was taken to a hospital for treatment of life-threatening injuries, said Anchorage police spokesman MJ Thim.
The vehicles collided at West 36th Avenue and C Street, and one of them "spun around" and hit the man, Thim said. One of the drivers also had minor injuries, Thim said.
The crash prompted police to close the eastbound lanes of West 36th at C Street for about three hours.
Police are still trying to determine who had the right of way, Thim said.
