Burning semi-truck causes morning delays on northbound I-5 in Seattle

A burning semi-truck is blocking the right lane of northbound I-5, north of Boeing Field on Wednesday, causing lengthy delays for morning commuters.

The Washington State Department of Transportation (WSDOT) reported the incident began at 4 a.m., with first responders arriving on scene.

There is currently about a 3-mile backup from the middle of Boeing Field towards the West Seattle Bridge, and roughly a 50-minute delay from Federal Way to Seattle, according to KIRO Newsradio Traffic.

“I could smell it by the way. When I drove by this morning, that thing is crispy,” KIRO Newsradio host Charlie Harger said.

WSDOT noted congestion is building up near the burning semi-truck, and there is no estimated time for the lane to reopen.

“Delays are likely as the morning commute gets underway,” WSDOT stated.

The Incident Response Team, Medical Aid, Fire Assistance, and the Washington State Patrol have all arrived on scene.

WSDOT advised travelers to allow ample time for their commute and to use caution while driving through the area.

Update: 5:30 a.m.: The right lane on northbound I-5 remains blocked north of Boeing Field (mp 162) due to an incident.

Crews are on scene but there is still no ETA to reopen.

Congestion is building in the area. Please give yourself extra time, use caution and expect delays. https://t.co/A9SYBnDb9J
