UPDATE 1-New York's George Washington Bridge re-opened after suspicious package - mayor

The George Washington Bridge in New York, one of the most heavily used spans in the world, was re-opened early Friday after a suspicious package spotted by a motorist turned out to be just a pipe, authorities and media said.

All lanes of the double-decker bridge were closed around 9 p.m. Thursday (0100 GMT Friday) after a motorist called in to police about a suspicious package, Mayor Bill de Blasio announced on Twitter. De Blasio urged travelers to seek alternative routes. Authorities re-opened the bridge around 12:30 a.m. to all traffic, the mayor later said.

The New York Post and other media reported that an object that looked like a pipe bomb was spotted by a motorist, forcing the shutdown of the bridge around 9 p.m. But the object was found to be inert, with no explosives, media reported.

Authorities re-opened both the lower and upper levels in both directions across the bridge, which links New York with New Jersey over the Hudson River.
