Driver killed in fiery head-on collision on NB I-5 in Skagit County

BURLINGTON, Wash. -- One person was killed when a vehicle on southbound I-5 crossed the grass median and collided head-on into a northbound box truck in Skagit County late Friday afternoon, authorities said. The fiery crash blocked most northbound lanes of the interstate north of Burlington.

The backup from the accident stretched nearly 6 miles north of Burlington at one point, the Washington State Department of Transportation tweeted.

At 6:35 p.m., the Washington State Department of Transportation tweeted the right lane of northbound I-5 at Bow Hill Road had reopened.

State Patrol trooper H. Axtman said it was unknown why the driver of the southbound vehicle lost control and crossed the median near Bow Hill Road and went into the northbound lanes. The driver was killed.

There were no immediate details on the driver of the box truck.
