TBTA Throgs Neck & Whitestone Bridges

New York, NY

This project provided an increase in safety and security for the Throgs Neck and Whitestone bridges by providing a fixed barrier system to thwart possible terrorist attacks or accidental collisions with tower legs. The fixed barrier system will be provided by Harbor Offshore Barriers and can stop a boat’s progress in milliseconds, yet remains fully capable of stopping a second or even a third swarm attack should one occur. This involves the installation of marine driven piles to support the steel fence requires to counteract collisions. The project also includes the installation of fire standpipe at each tower which requires night time work and phased construction to complete.
