Edmonton's roads were originally all named (as opposed to numbered) and arranged so that roads titled "avenues" ran north-south and "streets" ran east-west. The first move to a grid-style system began as the city expanded west - the streets west of Queens Avenue were switched to run on a north-south orientation with 1st Street (now 101 Street) being west of Queens Avenue, and the street numbers increasing further west (i.e. 10 Street was one block west of 9 Street).
West of Queens Avenue, the avenues also switched (running in an east-west direction); although, unlike the streets, the avenues were never numbered. This led to a confusing situation with avenues becoming streets despite no change in direction. For example, MacKenzie Avenue (now 104 Ave) became Boyle Street west of Queens Avenue, and Athabasca Avenue (now 102 Ave) became Elizabeth Street west of Queens Avenue. The view faces east and feature the now demolished Tegler Building and Macdonald Hotel in the background.
