At Km 1902.5 (Historic Mile 1221) you reach the Canada/USA (Yukon/Alaska) border. The US Customs post at Port Alcan is a few hundred yards further west. This photo looking east to the "Welcome to Yukon" sign and beyond, and the next 2 photos, were shot at the border in early June during a motorcycle ride from Whitehorse to Chicken and back. You can see a 3-part article with dozens of photos from that trip on The ExploreNorth Blog starting here.
