A serious accident in Chilliwack closed Highway 1 in both directions Friday morning.

Shortly before 6 a.m., DriveBC posted on social media that it was receiving “reports of a vehicle incident” between Annis Road and Highway 9.

Images shared in response to DriveBC’s post show a semicam lying on its side across the road.

Authorities closed the freeway in both directions and directed eastbound travelers to exit 129 and take Annis Road to Yale Road. Westbound travelers were directed to detour onto the 9 Freeway.

DriveBC Freeway cameras showed a long line of traffic backed up at the Annis Road exit.

“Expect delays,” DriveBC said.

CTV News has reached out to police for more information about the crash.

This is a developing story and will be updated.
