The original townsite follows a unique design. It is laid out on northeast-to-southwest and northwest-to-southeast roads. It is purported that the reason this was done was to allow sunlight to come into every room in the home at some point during the day. The northwest-to-southeast roads were numbered and called avenues, while the northeast-to-southwest roads were numbered and called streets. Only two central streets, the northwest-to-southeast Main Avenue and the northeast-to-southwest Shoshone Street, were named. This system created situations where one side of a street may have an entirely different address than the other, and where the corner of "3rd and 3rd," for example, was in more than one location. In 2003 the numbered northeast-to-southwest streets were renamed to alleviate decades of confusion. Later city roads, such as Blue Lakes Boulevard, Addison Avenue, and Washington Street, are laid out in standard north–south and east–west orientations. Addison Avenue honors Addison T.
