Two traffic incidents caused major back-ups during the morning commute.
A pedestrian involved collision on southbound I-5 at State Route 526 has been investigated by Washington State Patrol. All lanes were reopened around 8 a.m., but a several mile back up remained through much of the next hour.
The accident happened before 6 a.m. The pedestrian was pinned under a car and his clothes and back pack littered the road. His condition was very critical when he left the scene, according to KIRO Radio reporter Chris Sullivan, at the accident site.
Troopers believe the man was hit by two cars after darting or possibly running into the road.
Trooper Mark Francis says the second driver saw the first car and thought himself 'this guy is having a tire blow out.' "That's when he sees the pedestrian, he strikes the pedestrian head on, he comes to a stop, the pedestrian becomes entrapped underneath his vehicle."
The Washington State Department of Transportation recommended State Route 99 as an alternative route while congestion through the area cleared.
Meanwhile, an overturned semi truck on westbound I-90, just east of I-5 also caused early morning grief for commuters.
WSDOT crews worked to open express lanes early to alleviate some traffic congestion. KIRO Radio traffic reporter Kimi Kline reported State Route 520 as a quick alternative to I-90.
Crews were able to turn the semi upright and tow it away around 6:45 a.m. All lanes of westbound I-90 were reopened just before 7 a.m.
