A major crash on the Sea-to-Sky Highway today is causing severe traffic disruptions near Horseshoe Bay, after a commercial tractor-trailer rollover blocked southbound lanes and reduced northbound traffic to a single lane on Highway 99 Thursday afternoon.

The collision occurred at approximately 12:05 p.m. PT on Highway 99, about 600 metres north of the Horseshoe Bay ferry terminal, according to early reports from motorists and traffic monitoring services.

Witnesses say the commercial vehicle rolled onto its side, completely blocking southbound lanes and forcing northbound Sea-to-Sky traffic into single-lane flow.

Emergency response ongoing on Highway 99

RCMP and BC Highway Patrol remain on scene as recovery operations continue. Photos circulating on social media show emergency crews working around the overturned truck, suggesting a complex cleanup effort that could extend through the afternoon commute.

The Sea-to-Sky Highway is the primary route connecting Metro Vancouver with Squamish, Whistler, and other Sea-to-Sky communities, making the disruption especially challenging for local residents, commuters, and travellers.

Heavy Sea-to-Sky traffic delays reported

Drivers report significant traffic delays in both directions, with congestion stretching well beyond the crash site.

“Traffic is barely moving,” one motorist told 1130 NewsRadio, noting that debris had spread into the northbound lanes while crews worked to clear the roadway.

The incident is already impacting Sea-to-Sky traffic conditions, particularly for drivers travelling between Vancouver and Squamish during peak daytime hours.

No confirmed injuries at this time

As of publication, no official information has been released regarding injuries or the condition of the truck driver. Authorities have not yet confirmed what caused the rollover, nor have they provided an estimated timeline for reopening all lanes.

What Sea-to-Sky drivers should expect
