Photos: Crowds gather for 'Manhattanhenge'

The sun sets over 42nd Street at the Park Avenue overpass in New York's Manhattan borough during a phenomenon known as Manhattanhenge, Wednesday, July 11, 2012. Manhattanhenge, sometimes referred to as the Manhattan Solstice, happens when the setting sun aligns with the east-to-west streets of the main street grid. The term references Stonehenge, at which the sun aligns with the stones on the solstices in England. (AP Photo/Jeffrey Furticella)
