The Washington State Patrol said via social media Sunday afternoon, September 28, 2014, to avoid I-90 in the Preston area.
WSP stated around 2:30PM that a multiple-car collision had stalled traffic in both directions due to a serious injury accident, possibly involving five vehicles.
It appears the accident occurred in the westbound lanes of I-90 just west of Preston exit 22, blocking all WB lanes, with two of the vehicles rolled-over and one on fire. Two lanes of eastbound I-90 were also blocked for a time.
WSP later stated that the multiple car collision involved four vehicles with injuries to multiple occupants, with the injuries “considered serious and not critical.” WSP said it appeared a Jeep traveling on eastbound I-90 crossed over the median into the westbound lanes causing the collision
As of 3:30PM, September 28th, WSP said the westbound lanes of I-90 near Preston would remained closed for 1-2 hours for the investigation and residents should be prepared for a lengthy closure as the accident scene was large and complex. Eastbound I-90 was open.
Drivers were being detoured off I-90 at exit 22 and routed through adjacent side roads, around the accident scene. The Washington State DOT also advised drivers to use westbound SR 18 as a WB alternate means of travel until the investigation was complete.
Alternated roads through the Snoqualmie Valley, including SR 202 in North Bend and Snoqualmie, Snoqualmie Parkway, North Bend Way and Meadowbrook Way were all jammed with drivers looking to avoid WB I-90 Sunday afternoon and evening.
