Walking is probably the best way to move around downtown during SXSW, and Austin has plenty of other choices to help you avoid festival gridlock. For festival attendees, SXSW has some solutions, too.
Even with these options, there will be more cars and more traffic on the roads during March 7-16. So consider filling your empty seats and meeting other SXSWers by downloading RideScout or Carma today. Use either one to offer a ride to downtown Austin or between events, or to find others who are offering rides. Getting around together is now very easy and a safe way to become part of a solution to traffic.
