Two 20-year-olds who were in a van that pulled in front of a semi-trailer truck were taken to Harborview Medical Center in Seattle with injuries after a collision on U.S. Highway 101 just south of Mill Point Wednesday afternoon.

The Washington State Patrol said the highway-closing crash was caused by a 25-year-old Devils Lake, North Dakota man after he failed to yield the right of way to a semi-trailer truck driver who was headed north on US 101 just before 3 p.m. Feb 2.

The collision left the highway partially blocked to travelers for hours. US 101 was reopened to one-way, alternating traffic Wednesday evening.

The State Patrol said the driver who caused the crash was turning onto US 101 at Orcas Drive to go south.

His 1992 Chevrolet Astro van was struck by a semi-trailer truck driven by a 63-year-old Port Angeles man who was driving north.

After the collision, the van landed in the southbound ditch of US 101.

In addition to the driver of the van, a passenger, a 27-year-old Poulsbo man, was airlifted to Harborview for treatment.

US 101 near the Highway 104 interchange was completely closed to traffic Wednesday afternoon for the medivac airlift.

The highway was fully reopened at the crash site just after 6 p.m.

The van was totaled, according to the State Patrol.
