Fatal crash at Glenn Highway S Curves slows Anchorage commute Thursday

A multi-vehicle crash killed at least one person Thursday morning on the Glenn Highway S Curves near the Anchorage Weigh Station, prompting lane closures and delays for commuters traveling between the Mat-Su Valley and Anchorage.

Anchorage Police Department responded at approximately 8 a.m. The Alaska Department of Transportation and Public Facilities confirmed the response in a social media advisory posted at 11:15 a.m.: "On July 9, 2026 at approximately 8 a.m., APD responded to an injury collision on the S Curves of the Glenn Highway, which is located near the Anchorage Weigh Station."

As of that update, one southbound lane and two northbound lanes were open. APD warned that conditions remained hazardous even after lanes reopened. "Glenn Highway Southbound is now open, however, driving conditions remain hazardous," the department said in a public advisory. "Avoid unnecessary travel, if possible."

Alaska 511 logged a closure between mileposts 10 and 12 on the Glenn Highway. That segment is in the Eagle River area.

Background on the Corridor

The S Curves sit roughly 14 miles north of the Anchorage DOT Maintenance Station. DOT&PF maintains a road weather station at the site to monitor conditions year-round.

DOT&PF has said that real-time traveler information through Alaska 511 and active lane management are effective tools for managing safety during incidents.

What Is Still Unknown

APD confirmed at least one fatality upon arrival at the scene. Vehicle types and cause of the crash had not been officially confirmed by APD, the Alaska Department of Public Safety, or DOT&PF as of the 11:15 a.m. update.
