A wide-ranging police plan to safeguard the World Trade Centre site against bombs carried in vehicles is being criticised by residents.
People who live in the New York City neighbourhood surrounding the site say they fear new checkpoints and barriers could stifle their growing community and complicate traffic.
Lower Manhattan resident Kathleen Moore told a hearing yesterday that she feared ambulances would not be able to reach her building.
Neighbourhood community board chairwoman Julie Menin says the board wants to ensure the plan takes residents' needs into consideration.
Police commissioner Raymond Kelly says the police want to hear from residents.
It could take until 2019 to fully implement the plan.
The World Trade Centre is being rebuilt after the destruction of the twin towers in the September 11 2001, terrorist attack.
