New Yorkers can now enjoy more public space under the Brooklyn Bridge in Manhattan. The latest phase of “The Arches” opened on Monday, adding 15,000 square feet of park space to an area closed to the public for more than a decade, the city’s Department of Transportation announced. The space, now with lush greenery and new seating, had been closed for nearly 15 years while serving as a staging site for several bridge restoration projects. The Arches sits next to the Brooklyn Banks, a haven for skateboarders that partially reopened last year.
