Enrique Penalosa will help launch the San Francisco Great Streets Project, a campaign by the San Francisco Bicycle Coalition and the San Francisco Planning and Urban Research Association.
San Francisco's popular Sunday Streets program, which closes off city streets to vehicle traffic a few times a year in order to promote healthy physical activity, was modeled on Penalosa's "Ciclovia" system in Bogota.
Penalosa's model of urban development has been praised for a focus on more public spaces, a network of bicycle paths, greater pedestrian access and improved public transportation.
He will speak from 5:30 p.m. to 7:30 p.m. at the San Francisco Public Library's Koret Auditorium at 100 Larkin St.
The event is free and includes valet bicycle parking, according to organizers.
