UPDATE: 1 lane of Interstate 90 is open again. The other is staying closed for the night

Expect slow going if you’re heading west on Interstate 90 tonight.

Only one westbound lane will be open once you cross the Vantage Bridge, which spans the Columbia River at the border of Grant and Kittitas counties.

Crews are still cleaning up fuel that spilled out of a tanker truck around 11 a.m., said Washington State Patrol Trooper John Bryant.

Details about how the spill happened were not immediately available.

Both of the westbound lanes were closed for five hours, said the Washington State Department of Transportation.

People can avoid the area by using Highway 26 to reach Highway 243 and go through Yakima.
