For decades, planners and transportation specialists have debated how San Francisco’s most important street could be re-visioned to make it work better for transit, pedestrians, cyclists, shoppers, and those living on or near it. Now, as the Better Market Street Project moves forward with trial traffic diversions, the Art in Storefronts project, music and programming in public spaces, greening along sidewalks, and pedestrian safety improvements, San Francisco’s political class is intent on revitalizing the street for the long haul. Though the concrete vision for what Market Street will eventually look like is some ways off, there is more effort now than in many years to improve the public realm and ensure the street lives up to its great potential.
