The Top of the World Highway was completed around 1955, but the US performed border inspection services about 120 miles (190 km) away in Tok, Alaska until 1971, when it built a log cabin-style inspection station at the border. In 2001, the US and Canada constructed a joint border inspection station, where inspectors from both countries occupy a single facility. A line painted on the floor in the building marks the US-Canada border.[2]
