The George Washington Bridge, which is spanning the Hudson River between Manhattan in New York City and the borough of Fort Lee in New Jersey was closed on Thursday night due to a bomb threat, authorities reported.

Axar.az reports citing the New York Post that the bridge was closed due to a pipe bomb threat, which was reported to be on the New Jersey side of the bridge, according to the police, cited by the New York Post.

Mayor Bill de Blasio announced on Twitter that the lanes of the bridge were closed due to a threat about a suspicious package.
