The latest sign of rehabilitation and renaissance of Upper Manhattan and the Bronx is the re-opening of the historic High Bridge this month. New York’s oldest standing bridge was originally used to transport water from the Croton River to the City. Just like an ancient Roman aqueduct the water was moved only by gravity. Now the bridge will offer a quick, convenient pedestrian and bicycle route from High Bridge (in the Bronx) to Upper Manhattan. The opening of the bridge will also be coupled with the opening of a greenway along the east bank of the Harlem River.
