Greenways are paths through linear parks with car-free space for bicycling and jogging. They are instrumental in connecting neighborhoods with open space to those that lack it, and providing car-free space for novice cyclists to bike in a safe environment. New York City currently has more than 100 miles of greenways, and a planned system of hundreds of miles more. Development and maintenance of greenways is hampered because different levels of government and different agencies manage the paths, entrances and parks that greenways run through. T.A. has called for a citywide Greenway Coordinator in the Mayor's office to bring all the different players to the table and ensure that greenways are aggressively maintained and developed citywide.

Here are some T.A. allies who are vigorously working to develop greenways across the city and region:
