It's an event that happens only a few times a year, but one definitely worth waiting for: the day when the George Washington Bridge's towers are lit.
The bridge's iconic criss-crossed steel towers are only illuminated during nine major holidays and special occasions—coinciding with the time the bridge flies the American flag, known as the world's largest free-flying U.S. flag.
Currently they include Martin Luther King Jr. Day, Presidents Day, Memorial Day, Flag Day, Independence Day, Labor Day, 9/11, Columbus Day and Veterans Day.
The towers are lit from dusk to midnight.
Some of the best views of the bridge from Manhattan can be found on the overlook in J. Hood Wright Park (between W 173rd and W 176th Sts from Ft. Washington to Haven Aves).
Or to see the bridge up close, follow the bike path on the Hudson River Greenway to Fort Washington Park, which then snakes around to bridge's east towers.
