The Intro to SeeClickFix on atlantabike.org reads, "We've been waiting for a tool like this one for a long time, and it's finally here! Developers in New Haven, Connecticut, created SeeClickFix.com to allow communities everywhere to report, track, and ultimately fix hazards in the public right of way. Here at ABC, we are often asked to intercede on behalf cyclists with complaints or concerns about parallel grates, disappearing bike lanes, dangerous bridge gaps, etc. I believe SeeClickFix will help us better track your needs and the responses we receive, while turning cyclists across Atlanta into their own best advocates for improvements! Please read more to see the map and to add any hazards you've experienced."
