The Trans-Canada Highway reopened to traffic in both directions late Monday morning after a rock slide just east of Golden, B.C. closed the major route in both directions for hours.

The falling rock knocked down power lines and prompted the closure 16.7 kilometres east of the town of Golden, according to DriveBC.

Golden is located about 260 kilometres west of Calgary.
