SEATTLE—A person was killed Saturday morning on Interstate 5 in Mountlake Terrace when their vehicle struck a mattress on the freeway, swerved, then was hit by a semitruck, according to the Washington State Patrol.
Northbound I-5 was blocked between the northbound off- and on-ramps at 220th Street Southwest, with motorists diverted around the scene. The road reopened within a few hours.
The State Patrol received a call at 6:35 a.m. about a “truck losing a mattress in the roadway,” said patrol spokesperson Trooper Jacob Kennett. The caller reported that the truck had pulled over to the shoulder but gave no description of the truck, Kennett said.
Minutes later, a Nissan Maxima traveling north struck the mattress, Kennett said. The driver lost control, swerved to the right across traffic lanes, then left into the path of a semitruck, which hit the driver’s door.
