The new entrance to the Bowling Green Station 4 and 5 subway lines protects riders, and the escalator, from snow, rain and wind. Sited between the landmarked Customs House and historic Bowling Green Park, the new station canopy is a dramatic, transparent, curved steel and glass structure sensitive to its historic surroundings. Five stainless steel ribs project over the entrance, supporting a segmented glass roof and side wall panels. A granite base encloses the entrance stair and escalator and supports the canopy. The project involved close coordination with multiple public agencies and community organizations.
