WASHINGTON (AP) - The District is brightening up the city's alleys with new lights that are expected to last longer and cut emissions.
The D.C. Department of Transportation is wrapping up an effort to replace 1,360 incandescent bulbs with light-emitting diode fixtures along the alleys it maintains. Mayor Vincent Gray and other officials will install one of the last fixtures in the project on Monday in the Mount Pleasant area.
The department hopes the effort will help it save on maintenance and energy costs. It estimates that the new lights will save nearly 600,000 kilowatt hours of electricity annually. The LEDs are also expected to cut carbon-dioxide emissions by 719 tons.
