John Portman Boulevard and Peachtree Center Avenue Intersection Downtown Atlanta is getting the first intersection of two separated, two-way bike lanes in the United States. This intersection design offers increased safety for people on bicycles. The design separates pedestrians from bicyclists and will require some bicyclists to stop and wait within the bike lane to make turns. The main challenges the design needed to accommodate were:
1. Create a safe way for bicyclists riding north or south on Peachtree Center Avenue to turn east onto John Portman Boulevard (toward Piedmont). 2. Create a safe way for bicyclists riding east or west on John Portman Boulevard to turn south onto Peachtree Center Avenue (toward the State Capitol). 3. Ensure that motorists turning left from John Portman to Peachtree Center do not turn into the protected bike lane. 4. Designing an intersection that slows down users so that people have time to react safely to one another. 5. Provide space for bicyclists to stop safely without disrupting the flow of other bicyclists. Toole Design Group, a leading bicycle planning and engineering firm, assisted in creating a full range of possibilities for the City to consider. The City has choosen to install the following features to meet the design goals (see reverse side). If you have any questions, please contact: City of Atlanta, Chief Bicycle Officer, Becky Katz
