The upgrade to the Sea to Sky Highway will have an effect on West Vancouver, particularly the proposed overland route by Horsehoe Bay.
More information can be found from the British Columbia's Ministry of Transportation site, which includes contact information for road delays,and detailed reports on the project.
The West Vancouver District web site provides a map of the options considered, and their impacts.
If you haven't driven up the highway lately, you will be surprised at what has already been done and the size of the project.
