Highway 2 four miles east of Reardan is now reopened.
The highway was closed in both directions earlier this evening because of a semi-truck fully engulfed in flames, the Washington State Patrol said.
The truck, hauling hay, caught fire near the Spokane and Lincoln county line about 5:30 p.m. The hay truck will remain on the scene for awhile longer, but is not blocking the roadway, WSP said.
