For the second time in a week, a region of British Columbia is being affected by mudslides.

This time it is residents of the Squamish-Lillooet area in the south central Interior of B.C. which have been isolated after parts of a highway became buried under piles of wet gravel.

Residents of several communities in the region, which is located to the northeast of Whistler, were cut off from access to gasoline, medicine and food when a mudslide buried parts of the Lillooet Pioneer Road, near Carpenter Lake, last Saturday.

B.C. Ministry of Forests officials and a highway contractor have struggled to reopen the Lillooet Pioneer Road, which is also known as Route 40.

The communities which have been cut off from regular services, include Tyax, Gold Bridge, Gun Creek Road and Bralorne.

An alternate route, the Hurley River forestry road, was also closed due to instability.

The mudslides in the Squamish-Lillooet area come just days after the Trans-Canada Highway was shut down west of Golden, due to a mudslide in Glacier National Park.
