Both lanes of Interstate 5 were closed south of Olympia for three hours and 32 minutes Wednesday evening after a passenger car hit a southbound semi-truck, struck the Jersey barrier and came to rest in the northbound lanes.
The Washington State Patrol responded to the crash just after 7:50 p.m. on Nov. 30.
The passenger vehicle was traveling in the far left lane of southbound I-5 when, just south of 113th Avenue SW in Olympia, it merged into the center lane and struck the semi-truck.
The passenger vehicle then swerved to the left, struck the Jersey barrier and crossed into the northbound lanes, ultimately blocking all three lanes of northbound I-5.
The semi-truck came to rest on the right shoulder of southbound I-5.
No injuries were reported in the crash. The cause of the crash is under investigation, though Washington State Patrol has confirmed that drugs or alcohol were involved.
The driver of the passenger vehicle, identified by Washington State Patrol as a 63-year-old man from Willamina, Oregon, is facing possible DUI charges.
Both directions of I-5 were closed at exits 95 and 99 while crews cleared the wreckage.
