New York City's Triborough Bridge was shut down on Wednesday night after police said a truck, smelling of gas, was found abandoned on the busy thoroughfare.
New York Police Department spokesman Paul Browne said a worker on the bridge that connects the New York City boroughs of Manhattan, Queens and the Bronx found the vehicle abandoned by its driver and apparently smelling of gas.
The New York police bomb squad was investigating the vehicle, law enforcement sources said.
Browne said the vehicle was a U-Haul rental truck with Arizona license plates. It was left on a Manhattan-bound service road leading from the Bronx, he said. Fire officials were responding.
The closure of the span, also known as the Robert F. Kennedy Bridge, came days after a failed bomb attack on New York's Times Square that has heightened security concerns in America's most populous city.
Prosecutors on Tuesday charged Faisal Shahzad, 30, a naturalized U.S. citizen born in Pakistan, with five counts, including attempting to use a weapon of mass destruction and trying to kill and maim people within the United States.
He is accused of driving a crude homemade bomb of gasoline, propane gas, fireworks and fertilizer into Times Square on a warm Saturday evening.
New York Police Commissioner Ray Kelly said the Times Square plot was the 11th thwarted attack on New York City since hijacked airliners destroyed the World Trade Center's twin towers on September 11, 2001, killing more than 2,600 people.
Update: Cnn and fox news report that no bomb was in the truck. Police about to open bridge again soon. Investing pending on why the vehicle was left alone.
