Illustrating a linear, pedestrian-oriented park connecting Union Square, Madison Square, Herald Square and Times Square, the Green Line is a historical, ecological, and geomorphological investigation of the borough of Manhattan. Once the major commercial and surface transportation spine of the city, Broadway has changed. Today, it is a subway street, a bike route, and, increasingly, a pedestrian-dominated street. Recognizing a need for publicly accessible open space throughout the contemporary, post-industrial city, Perkins Eastman envisioned sustainable and inviting network of landscaping, playgrounds, dog runs, a running and bike path, performance areas, and gathering space—all which benefit the environment and local economy alike. Reimagining Broadway as a memorable recreational destination, The Green Line gives urban space back to the millions of New Yorkers and visitors who would use it in a new way every day.
