Transportation Alternatives’s bold plan to claw back a quarter of the city’s public space from the domain of automobiles is already making waves in the mayoral race, with five top progressive candidates backing the safety and quality-of-life initiative. Others reacted tepidly or not did not return responses. Called “NYC 25 by 25,” the plan asks mayoral candidates to commit to dedicating 25 percent of the space now designated for vehicles — including 19,000 miles of roads and three million on-street parking spaces — as space for people by 2025 so that New Yorkers might have room to recover from (and thrive after) the COVID-19 pandemic, which has highlighted the city’s lack of equity when it comes to active transportation and green space.
