The Parks Highway was closed at Milepost 152 Monday night after two people were killed and one seriously injured in a head-on collision, the Alaska State Troopers said.
At 5:45 p.m., troopers were called to the scene of the crash a few miles north of the Byers Lake Campground, AST spokeswoman Megan Peters wrote in an email.
As of 7 p.m., the highway was closed in both directions, Peters said. She had no timeframe for when it would reopen.
Troopers are investigating the cause of the collision.
LifeMed Alaska was also called to the scene, Peters wrote.
Peters did not immediately provide descriptions of the vehicles thought to be involved in the crash or identify the people killed.
A woman answering the phone at the trooper detachment in Cantwell said no troopers were available to speak because they were out of cellphone range.
