UPDATE: 10:20 p.m.

The semi crash has now been cleared and the highway reopened, DriveBC reports.

A crashed tractor-trailer has closed the southbound lanes of the Coquihalla Highway.

DriveBC reports the highway is closed two kilometres south of the Inks Lake exit, near Kamloops, on the way to Merritt.

A contractor is said to be en route to assess the incident.

It's estimated it will take three to four hours to clear the scene.
