Fictional Interstate Highways

An Interstate (Japanese: 州間高速道路 Shūkan Kōsoku Dōro) is a highway, except for lettered ones, runs throughout the continental United States. Their system was planned by Dwight David Eisenhower (Japanese: ドワイト・デビッド・アイゼンハワー Dowaito Debiddo Aizenhawā) during his presidency. These are the following freeways:
Interstate 1 (or I-1, Japanese: 州間高速道路1号線 Shūkan Kōsoku Dōro Ichi-Gōsen), as its number implies, is the westernmost Interstate in the United States. Its southern end is US Route 101, and its northern end is at the Canada-United States border.
Interstate 100 (or I-100, Japanese: 州間高速道路100号線 Shūkan Kōsoku Dōro Ippyaku-Gōsen), as its number implies, is the continental United States' northernmost Interstate highway, and is the closest to the US-Canada border. Its multiples, like every other Interstate assigned a number greater than 100, are auxiliary. Its western and eastern ends are Interstates 1 and 95 respectively. It crosses all the Great Lakes except Lake Michigan. Interstates 200 to 800 are loops and/or bypasses of this controlled-access highway, while Interstates 300 to 900 are spur routes.
