Driver arrested after head-on crash kills 2 people on SR 18

PRESTON, Wash. -- Troopers arrested a driver after two people were killed Friday morning in a head-on crash on SR 18 in east King County.

Washington State Patrol Trooper Rick Johnson said both directions of the highway were blocked near Tiger Mountain Summit starting at 5:15 a.m.

Johnson said a pickup truck heading westbound crossed the centerline and struck a car. Both passengers died at the scene.

The pickup driver was first taken in serious condition to Seattle's Harborview Medical Center. Johnson said the man is under arrest for investigation of two counts of vehicular homicide.

Q13 News traffic expert Adam Gehrke says eastbound drivers can are being detoured onto Issaquah-Hobart Road. Westbound drivers should use I-90.

SR 18 had reopened by 11:00 a.m.
