On the Throgs Neck Bridge this morning a worker was “struck by the boom from a boom truck,” says the MTA, and was killed. (Earlier reports had him falling from the bridge.) The worker, not yet identified, was pinned under the boom until firefighters arrived to lift it off. He was pronounced dead at the scene. Several lanes are closed as a result and drivers are re-directed to the Bronx-Whitestone and the RFK/Triborough Bridges.
