Lighting Maintenance Inc. maintains thousands of miles of roadway lighting. Additional services include the preventative maintenance, repair, and replacement of bridge span navigational lighting below the bridge deck and navigational lighting on channel fender systems. This includes all circuits, conduits, fixtures, lamps, distribution boxes and all its parts. These activities involve working from the bridge deck, requiring traffic control and/or working from navigable water ways. We maintain lighting on interstate highways from north Baltimore, Maryland, to Richmond Virginia, to Hampton, Virginia.
