City buses and a 16-stop Light Rail Transit (LRT) system cover most of the city. The fare is $3.20. Buses operate at 30-minute intervals between 5:30am and 1:30am. Check out the excellent transit planning resources at www.edmonton.ca. Daytime travel between Churchill and Grandin stations on the LRT is free.
Between mid-May and early September you can cross the High Level Bridge on a streetcar ($5 round-trip, every 30 minutes between 11am and 10pm). The vintage streetcars are a great way to travel to the Old Strathcona Market (103rd St at 94th Ave), where the line stops. Or go from Old Strathcona to the downtown stop, next to the Grandin LRT Station (109th St between 98th and 99th Aves).
