The Infinite Broadway project reimagines Broadway in Manhattan as a 13-mile long public square. By excavating below the street and taking advantage of existing basements, a new horizontal public space and landscape is created. The square is designed with varying characteristics along its length to reflect the diverse neighborhoods it passes through, including plazas, markets, parks, arcades, and rooftop areas at different levels. This transforms Broadway from a congested road into a slow, pedestrian-focused public space running the length of the island.
