Me in front of the welcome sign on the Alaskan side. I was however crossing into Canada on my way to Dawson City. The U.S. and Canadian customs are located in their respective small buildings at the border which is open May 15th to September 15th. There is a time difference of 1 hour to observe when crossing the border.
The Top of the World Highway connects Dawson City with the Taylor Highway in Alaska. There is a free ferry service crossing the Yukon river at Dawson City. The canadian side of the Top of the World Highway is sealed and in significantly better condition than the Alaskan side and the Taylor Highway, but is it still a winding road with many steep hills. The name derives from the road mostly following the hilltops and often providing stunning views over the surrounding valleys.
