“We had to close I-90 due to the amount of smoke that was crossing over,” WSP Trooper Jeremy Weber told KIRO Newsradio. “It was just a little bit too dangerous for traffic at this point.”
Weber said one fire was between mileposts 81 and 84, then there were two separate fires at milepost 76 and milepost 78.
“We just made the decision to close [I-90] down, which is something we don’t like to do, and that’s the last thing we want to do, is shut down I-90,” he said. “Safety is paramount.”
Cause of the fires along I-90 under investigation
As for what sparked the fires, Weber said he’s heard different scenarios.
“I heard one time that there might be a trailer that lost a wheel and was dragging an axle that might have caused a spark. We don’t know until we can actually get in there and do some investigation,” he shared.
WSP also doesn’t know if the fires are connected.
Drivers advised to use alternate routes
Those traveling on I-90 were advised to plan ahead and seek alternate routes.
“If you are traveling, make sure you check the roadway. Check WSDOT. You can get on there and check to see any closures,” Weber said.
WSDOT previously reported there were delays on I-90 west due to several fires along the road.
