Trans-Canada Highway still closed north of Hope

The high risk of an avalanche forced the closure of the Trans-Canada Highway from Boston Bar to Lytton early Thursday morning.

The route is being assessed by technical engineers, but an update issued at 8 p.m. PT said the route remained closed and there was no estimate when it would reopen.

The Coquihalla Highway 5 and Highway 8 are the recommended alternate routes.
