The following is a list of the east–west arterial thoroughfares in the city of Edmonton, Alberta. Numbered avenues run east-west with avenues numbers increasing to the north. In 1982 a quadrant system was adopted. Quadrant Avenue (1 Avenue; only constructed west of the river), along with Windermere Boulevard and the south leg of Anthony Henday Drive, dividing the north and south quadrants. Edmonton currently has three quadrants: northwest (NW), southwest (SW), and northeast (NE); the vast majority of the city falls within the northwest quadrant. Addresses on 41 Avenue and south have been encouraged to include NW to avoid confusion with addresses in the SW quadrant.
