A Kennewick woman is dead following a single-vehicle accident in Kittitas County on Thursday afternoon.

The Washington State Patrol reports it occurred at just before 4 p.m. on Interstate-90 about 15 miles east of Kittitas, when the 23-year-old woman lost control of the sedan she was driving, went off the roadway, and crashed.
