Wildfires close Highway 93 from Radium Hot Springs to Alberta border until Aug. 5

Highway 93 from Radium Hot Springs, B.C. to the Alberta border will remain closed until Sunday, Aug. 5, at 10 a.m. PT at the earliest.

DriveBC says wildfires burning in close proximity to the highway have made it too dangerous for motorists to drive that stretch of road.

The highway was closed Wednesday.

Parks Canada is currently managing three lightning-ignited wildfires in Kootenay, Yoho and Banff national parks.

None of these fires pose a risk to local communities, but there is dense smoke in the area and limited visibility.

All trails, backcountry campgrounds and day-use areas from the Rockwall Trail south to the Dolly Varden Trail are closed at this time.

A fire ban is in place for Kootenay, Yoho and Banff national parks due to the elevated fire danger.
