The Seward Highway is now open in both directions near Girdwood following a fatal collision Tuesday, an updated release from the Anchorage Police Department said Wednesday.

The collision closed the Seward Highway Tuesday evening. The closure lasted until around 4:30 a.m. Wednesday.

The Girdwood Fire Department's Facebook page reported just before 9 p.m. Tuesday that the Mile 91 collision was fatal, soon after an APD message announcing that the highway was closed about 5 miles south of Bird Point.

APD spokesman MJ Thim said the collision involved a pedestrian, who "may have been struck by several vehicles."

"The pedestrian was struck and pronounced dead at the scene," police wrote in a statement just before 10 p.m. Tuesday.

Views from Department of Transportation and Public Facilities road cameras showed traffic backing up in the area overnight.

APD asked drivers to avoid the area as officials investigated the scene.
