Bridge & Tunnel Environmental Initiatives

The Port Authority's six bridges and tunnels connect tens of millions of commuters to their workplaces and homes every year. We are committed to making those facilities as environmentally responsible as possible.

LED Necklace Lighting on the GWB

We are replacing the decorative bridge necklace lighting of the George Washington Bridge with customized, energy efficient light-emitting diode (LED) fixtures. The project is being carried out through the Port Authority's long-term energy services agreement with the New York Power Authority (NYPA).

LED lighting in the Holland Tunnel

We are also developing customized LED fixtures for the Holland Tunnel. This too is through the NYPA. LED lighting is also being considered for the Lincoln Tunnel and the Staten Island Bridges.

Boiler Control Demonstration Project

We are currently planning a demonstration project at the Holland Tunnel. The project uses computer-controlled heating system economizers that reduce fuel consumption by at least 10 percent, reduce wear on parts, and reduce emissions by 40-50 percent. If the demonstration is successful, the PA will identify other facilities that could benefit from the devices.
