The closure of the Sea to Sky Highway north of Vancouver is starting to affect the supply of fuel in the resort community of Whistler.

The main route into town, Highway 99, was shutdown by a massive rock slide late Tuesday night, and is expected to remain closed for several days while crews clear the debris.

Now the only route into town involves a seven- to 10-hour detour along some less travelled highways.

By noon Thursday the Husky station in Whistler and the Shell station in Pemberton were both out of fuel as visitors gassed up their vehicles in preparation for a long drive home. More fuel supplies were expected to arrive later Thursday afternoon.

But to the north, businesses in Lillooet were looking forward to an influx of people heading to and from Whistler through the Fraser Canyon route.

The mayor of the district, Christ'l Roshard said she has already seen an increase in restaurant and gas station business.

"We've had a lot of traffic in the last five or six days, first with the Pemberton Music Fest, and now with this unfortunate incident with the slide down near Furry Creek," said Roshard.

Olympic events could be rescheduled

Meanwhile the Vancouver Olympic Organizing Committee says it would consider re-scheduling events if there was a problem with the Sea to Sky Highway during the Games.

This week's rockslide has some questioning whether Olympic organizers are prepared for major problems, but Vanoc's executive vice-president of venue management Cathy Allinger said organizers are working on a contingency plan.

"Winter Games are interesting because they have weather to deal with as well and so events aren't always on they day they are planned…. There is an opportunity to possibly postpone the event," said Allinger.
