The RBC GranFondo Whistler returns this weekend, bringing with it thousands of cyclists travelling from Vancouver to Whistler.
The event, which has not run since 2019 due to the COVID-19 pandemic, will see rolling lane closures and speed limit reductions between Stanley Park and up the Sea to Sky Highway throughout the day Saturday, Sept. 10.
More than 6,000 cyclists from 25 countries are expected to make the 122-kilometre, mostly uphill journey, according to organizers.
Vancouver and North Shore detours
Between 5:30 and 8:30 a.m. the Stanley Park Causeway and Lions Gate Bridge will be closed northbound, while one southbound lane will remain open.
Westbound Marine Drive will be closed between Capilano Road and Taylor Way. Drivers will be detoured down Lower Capilano Road to Welch Street during that time.
The intersection of Taylor Way and Marine will have intermittent closures until 10 a.m. Both eastbound lanes of Highway 1 between Taylor Way and Horseshoe Bay will be closed from 5:30 until 10 a.m., during which time Marine Drive will be the only eastbound option.

A variety of traffic safety measures will be in effect, according to organizers, including lowering the speed limit to 60 kilometres/hour on sections of Highway 99 between Horseshoe Bay and Whistler, single-lane traffic on various stretches of Highway 99, and a few closures and detours.
Sea to Sky RCMP say support units will also be present along the route, particularly near the four designated rest stops along the route: Porteau Cove, Alice Lake, Salt Shed, and Brandywine Chain-Up area.

Squamish motorists will experience a series of intermittent delays between 8 and 8:30 a.m and 10:30 a.m. to 12:30 p.m., as well as full closures between 8:30 a.m. and 10:30 a.m. along Highway 99 between Valley Drive and Depot Road.
According to organizers, traffic signals will be flashing and traffic movements, both to and from the east side of Highway 99, will be restricted and or closed.

Motorists here can U-turn at Depot Road for southbound access to the highway.

Police also encouraged Sea to Sky residents and visitors to plan for extra travel time, and underscored that the detachments have resources dedicated to the event to facilitate traffic flow and safety.
“We hope riders, supporters, and organizers have a safe and fun event,” said Cpl. Angela Kermer, Sea to Sky RCMP's media rrelations officer, in a release. “We also thank drivers in advance for their patience and attentiveness as the event progresses throughout the day.”
"Motorists are also advised to plan their travel well in advance, drive with caution and follow signs," the event's website reads, noting that there will be a few "traffic pattern changes" implemented throughout the day. "Thank you for your cooperation and for supporting all of the volunteers, spectators, and the athletes who have trained so hard for this day. Together we can create a successful day for all."
