A serious crash has closed a section of the highway near Agassiz, British Columbia, investigators say.

Corporal Dave Noon said in a social media post that the Lower Mainland Integrated Collision Analysis and Reconstruction Service team – or ICARS – was dispatched to Highway 7 for the collision.

“The highway is closed and will remain closed for several hours as we investigate,” Noon’s post, shared around 5:30 a.m., said. “Expect significant delays.”

DriveBC said the highway was closed east of Agassiz, near Seabird Island, and drivers were advised to use Highway 1 instead.

No details were given on how many vehicles were involved in the crash. According to the RCMP, ICARS is called to crashes that result in serious injury or death.
