http://www.nbcnews.com/id/53159067/NACHES, Wa. - The Washington State Department of Transportation says part of Highway 12 near Naches is closed because of a washout on the roadway.
A 45 mile section of US-12 is closed in both directions from the Oak Creek feeding station, about one mile west of the State Route 410 Junction to the State Route 123 Junction just west of White Pass.
The closure runs through Yakima and Lewis Counties over White Pass, from milepost 138 to milepost 183.
Drivers can take State Route 410 and State Route 123 as an alternate route. However, commercial traffic is prohibited on the alternate routes.
DOT crews are working to clear the roadway near milepost 154, but they aren't sure when the stretch of US 12 will open again.
