The Canada - US border is about 100 miles (160 kilometers) from Seattle-Tacoma International Airport. At the airport the highway splits, with I 5 going into Seattle proper and Highway 405 continuing north to Whistler. Take Highway 405, unless you are heading into Seattle. The 405 eventually rejoins Interstate 5, but not until you're safely away from Seattle. From there, you have another 80 miles (128 km) to the border. Look for signs for the towns of Everett, then Bellingham, then Blaine is right at the border.
Scenic Route via Downtown Vancouver
Coming from the U.S., the entry point is the Douglas Border Crossing which features the Peace Arch. Once in Canada, the highway becomes Highway 99. Follow Highway 99 through the Massey Tunnel and proceed straight to enter Vancouver via the Oak Street Bridge, about 20 miles (32 km) from the border. Once on the bridge stay in the right lane and watch for the Granville Street exit (right off the bridge). Follow Granville Street to downtown Vancouver via the Granville Street Bridge. Once on this bridge, take the Seymour Street exit and proceed along Seymour to Georgia Street (6 to 7 blocks), turn left. Georgia takes you west through downtown and directly over Lions Gate Bridge to North Vancouver.
As you approach the far side of Lions Gate Bridge look for the West Vancouver exit. It's a gradual merge left at the end of the bridge. The exit circles around under the bridge onto Marine Drive. Stay in the right-hand lane, over a small bridge and quickly to a stop light at Taylor Way. Turn right and head up the hill where you'll see Highway 1 before you. Merge to the left under Highway 1, turn left immediately under the overpass. As you approach Horseshoe Bay, slow down and watch for the exit for Squamish and Whistler. Whistler Village is about 90 minutes from this point.
Direct Route, Bypass City of Vancouver
As you approach the Canada-USA border, take Exit 275 (about a mile before the border) off Interstate 5 onto Pacific Highway. The Pacific Highway Border crossing is also known as the truck crossing. Once across the border it's called 176th Street or Highway 15. Follow Highway 15 approximately eight miles north to Highway 1, the Trans Canada Highway. Take Highway 1 westbound. Make no turns. You'll zoom through the north-eastern municipalities of Greater Vancouver, motoring across the Port Mann Bridge over the mighty Fraser River and eventually the Iron Workers Memorial (Second Narrows) Bridge crossing Burrard Inlet. Watch for the exit for Squamish and Whistler. Whistler Village is about 90 minutes from this point.
