Road clearing to take several days

The City of Kamloops says crews have been working all night clearing major arterial roads prior to focusing on residential and side streets, and continued snowfall is keeping crews busy.

"We're fighting it hard but definitely not making the kind of headway in getting down to bare asphalt," said Glen Farrow, the city's manager of streets and environmental services, speaking on CBC's Daybreak Kamloops.

"Within storm mode, the focus is definitely to continue to focus on those main [roads]."

A similar message has been issued in Prince George, with the city warning even without new snow it could take until Friday for residential roads to be fully cleared.
