History of Tertiary Highway 807 (#2):
The second Tertiary Highway 807 was a temporary designation applied to the new highway that was under construction between Atikokan and Ignace in the 1980s. Construction began on the new highway in 1982 at the Atikokan end of the proposed route. In 1986, construction began on the northern section of Highway 807, immediately south of Highway 17. In 1988, the north and south portions of Highway 807 were connected, and the new highway was officially opened to traffic in September, 1989. The highway was renumbered from Highway 807 to Highway 622 at that time. The opening of Highway 807 (Highway 622) in 1989 marks the completion of the last major long-distance highway link in Northern Ontario. A different, unrelated Highway 807 existed in the Smooth Rock Falls area during the 1960s and 1970s.
