Injury collision prompts six-hour I-5 closure near Tumwater

A Saturday morning collision closed northbound Interstate 5 near Tumwater for more than six hours, according to the Washington State Patrol.

The four-car collision occurred about 8 a.m. at Milepost 100, Trooper Guy Gill said. One patient was airlifted to Harborview Medical Center.

Crews shut down I-5 and set up a detour at 93rd Avenue Southwest.

Gill said the situation was complicated when a group of drivers decided to drive the wrong way on the shoulder of I-5 in an attempt to exit and avoid the backup. Emergency vehicles were still using the shoulder to access the collision at the time.

“It created a very dangerous situation for the drivers and for emergency vehicles,” Gill said.

All northbound lanes of I-5 reopened to traffic at about 2:30 p.m.

This was the second major collision on I-5 near Tumwater on Saturday morning. A 43-year-old Oregon woman died from injuries sustained in a collision that occurred just before 6 a.m. A 26-year-old Seattle man was booked into the Thurston County Jail on suspicion of vehicular homicide.
