The lighting on the Claiborne Pell Bridge in Newport, RI, was retrofitted with high efficiency LEDs, which replaced the existing metal halide lighting on both the roadway and the cables.
The project was completed by Rhode Island-based Energy Source.
The Rhode Island Turnpike and Bridge Authority, which manages the span, expects savings of 321,000 kWh each year, resulting in $43,000 annually. The project also received utility rebates from National Grid. The combination of incentives and energy savings gave the project a simple payback of 3.7 years.
