Drivers travelling between West Vancouver and Whistler might notice significant delays this weekend, as a cycling event will bring some road closures.

The RBC GranFondo Whistler takes place this Saturday, and a traffic advisory from the province warns that closures could slow drivers down by up to three hours. 

Cyclists will travel over the Lions Gate Bridge, up Taylor Way and Cypress Bowl Road, along Highway 1 and Highway 99. They'll finish their race in Whistler.

Delays can be expected between 5:30 a.m. and 4:30 p.m. and the province says drivers should plan their trips in advance.
