Crossing freeway interchanges on a bicycle sucks, especially in this expressway-heavy place. However, it's possible to avoid that madness, especially if you want to connect from Central Phoenix to Scottsdale and/or Tempe. The secret is Oak Street, a mostly residential road that, thanks to the awesome pedestrian and bicycle overpass at State Route 51, makes it possible (and super fun) to ride to the two 'burbs. Heading east from Central Phoenix, you can link up with Oak in the Coronado neighborhood before crossing 16th Street and then SR 51. From there, there's a dedicated bike lane on the slightly busier street that links up with the Arizona Canal trail just east of 24th Street. Or you can keep riding, north of Papago Park to 68th Street (which will more or less lead you to Old Town Scottsdale) or all the way to Chaparral Park, which makes it possible to hit up north Scottsdale or Tempe.
