Semi-truck crash delays traffic on I-90

KITTITAS COUNTY, Wash. -- Traffic heading to Seattle on Interstate 90 is running smoothly again after an accident involving two semi-trucks backed things up for hours Monday afternoon.

The Washington State Department of Transportation posted a photo of the accident on Twitter. It happened just after noon near the Vantage Bridge.

Troopers say one of the trucks rear-ended the other. Investigators wrote up that driver for following too closely.

He was taken to the hospital. The other driver had minor injuries.
