The Coquihalla Highway is closed in both directions 15 kilometres south of Merritt,B.C. due to a vehicle accident, according to DriveBC.
The stretch of Highway 5 could be closed until 10 p.m. PT.
DriveBC says southbound traffic can detour the scene at exit 286, while northbound traffic can detour through Hope.
Vehicles can also avoid the closure by using Highway 3 or Highway 8 to Highway 1.
For parts of Sunday there was significant snow on the upper portions of the Coquihalla Highway between Hope and Merritt forcing commercial truck operators to use tire chains on their vehicles.
