Semi truck rollover makes a mess of traffic on Hwy. 101 in SLO

Southbound Highway 101 was shut down for five hours Thursday morning after a semi truck rolled over and leaked fluid all over the highway.

The full closure of the southbound lanes caused a massive backup as traffic detoured onto surface streets.

The crash was reported south of Los Osos Valley Road just before 8 a.m., according to the CHP’s incident information log. A semi truck overturned and began leaking fluid, according to the CHP.

At one point, the truck blocked both lanes of the highway, and approximately 2,500 gallons of fluid leaked out, according to CHP Officer Mike Poelking.

The San Luis Obispo County Regional Hazmat Team was called to the scene to evaluate the substance, according to Cal Fire. Authorities found that the substance wasn’t hazardous, but additional information was not immediately available, Poelking said.

No one was injured in the crash.

The southbound side of the highway remained closed until about 1 p.m.
