Eastbound I-90 remains closed in Kittitas County due to a 70,000-acre brush fire. Westbound I-90 reopened Friday about 7 a.m. Fast-moving flames are blowing heavy smoke over the roadway. The Washington State Department of Transportation (WSDOT) says eastbound I-90 is closed at exit 115 in Kittitas, eight miles east of Ellensburg. A detour has been set up at Vantage Highway for eastbound drivers. Officials will reevaluate the eastbound closure Friday afternoon, according to WSDOT. The fire nearly tripled in size in since early Friday morning. The Washington State Department of Natural Resources (DNR) said the fire is difficult for ground crews to access. The fire was 10 percent contained at 10 a.m. Friday morning.
