EVERETT — A semi truck overturned Thursday morning on a ramp to I-5 near Everett Avenue, spilling debris into the street and causing a 4½-hour closure.

State Department of Transportation traffic cameras showed the semi’s trailer over the edge of the ramp from westbound U.S. 2, following the rollover crash around 10:50 a.m.

The crash blocked traffic heading north onto I-5. The truck’s load — what appeared to be garbage — spilled onto a brushy hill and Everett Avenue below. The arterial street through the city was closed for about three blocks, according to Everett police.

Part of the bridge’s railing appeared to be hanging off the side. There was concrete damage on the ramp, according to the state Department of Transportation.

“This is going to be closed off for what I think will be hours,” Everett police officer Andrew Schuck said at the scene.

Several fire engines and ambulances responded, blocking off the ramp. Before closing off the street below, police cautioned pedestrians to avoid walking under the bridge.

The semi driver suffered minor injuries, Washington State Patrol trooper Kelsey Harding said.

Troopers were still investigating the cause, but it appeared only the semi was involved in the crash.

“It’s a tight ramp to make,” Harding said. “When you get a semi (crash), it’s tough to remove safely.”

There are still crews at the scene under ramp doing clean up. Everett Ave under the ramp is still closed.
