The 2019 Southern Arizona Bicycle Summit is sponsored by Cycling Advocates of Southern Arizona (CASAz) and held in conjunction with the area's premier cycling event - El Tour de Tucson.  Presentations will cover the City of Tucson's Complete Streets program, the kickoff of the League of American Bicyclist's Bicycle Friendly Driver program, the use of crowd-sourced data for bicycling planning decisions, and how bicycling advocacy can be fostered within your local governments. Join us for an afternoon of informative presentations and you will leave with a better understanding of what is going on in Southern Arizona and how you can help improve cycling in our communities.

Ms. Alarcon will outline the newly adopted Complete Streets Policy as well as other transportation initiatives her department is undertaking. Complete Streets are streets for everyone. They are designed and operated to enable safe access for all users, including pedestrians, bicyclists, motorists and transit riders of all ages and abilities. Complete Streets make it easy to cross the street, walk to shops, and bicycle to work.  Learn about how this policy will improve cycling in Tucson and about how you can become involved in making a difference in your community.
