Southbound I-5 blocked 11 hours, northbound blocked 9 hours after semi crash Monday

A crash that involved five vehicles, including four semi-trucks, shut down traffic in both directions on I-5 in Thurston County on Monday, according to the Washington State Patrol.

The State Patrol said Tuesday the multiple-vehicle collision blocked southbound I-5 for 11 hours and northbound lanes were blocked for nine hours.

But only one person, a 49-year-old Corvallis, Oregon man, was injured. He was taken to Providence St. Peter Hospital in Olympia.

It all began about 1:10 p.m. Monday. A 49-year-old Shelton man was headed north on I-5 near Maytown when troopers say he slowed for traffic.

The Corvallis, Oregon man was behind him. Troopers say he lost control of his semi and crossed all lanes of northbound I-5, hit the barrier and crashed through it into southbound I-5. His vehicle blocked three lanes of oncoming traffic.

A third vehicle, headed south, crashed into the Oregon man’s truck, then hit the barrier.

A fourth vehicle, also headed south, crashed into the Oregon man’s vehicle, too. A fifth vehicle, also headed south, drove off the road and into a ditch, according to the State Patrol.

The multiple-vehicle wreck is under investigation.

The backup on I-5 caused problems elsewhere in the county as drivers sought alternate routes and clogged other roadways, according to the Thurston County Sheriff’s Office.

A semi-truck crashed into the train trestle on Old Highway 99 near Offut Lake Road Monday night. No one was injured, the Sheriff’s Office said via social media.
