Eastbound traffic on I90 is being detoured around a semi-truck accident at Salnave Road about 13 miles southwest of Spokane, according to the Washington State Patrol.
The truck rolled over just before 6 this morning, trapping the driver inside.
One of two trailers was carrying sodium hydroxide, which is a corrosive material, but it doesn’t appears that the container leaked. Traffic is being diverted through Cheney on state Highway 904.
