Semi truck rollover forces overnight closure of SLO County highway
Emergency crews responded to a big rig rollover that blocked the highway along the San Luis Obispo/Santa Barbara county line late Tuesday evening.
At 10:42 p.m., a semi truck crashed and fell onto its side, closing both lanes of Highway 166 near Miranda Canyon Road, according to a post on X from Cal Fire.
Work crews were able to secure the scene and mitigate all hazards related to the incident, according to the post.
While there was an initial concern about a potential fuel leak that would have required a larger hazmat response, it was later determined to be a motor oil spill, which was contained to the roadway and cleaned up by the morning, Cal Fire public information officer Eva Grady said.
Cal Fire units were on scene all night, and the location of the crash was cleared by the morning, according to the post.
No other vehicles were involved in the crash, Grady said.
