Since about 1987,many new 'high profile' bridges built in Florida have incorporated decorative lighting features. Bridge lighting can be installed at relatively low cost. A key issue of bridge lighting systems is the ability to maintain such systems throughout the life of the structure. The Florida Department of Transportation has worked closely with local governments through Joint Party Agreements to obtain assistance with lighting maintenance . Although the maintenance and power costs of these lighting systems are relatively low, experience has indicated that routine maintenance is generally more responsive using local government forces.
Fixtures are generally either high pressure sodium or metal halide type luminaries.
High pressure sodium lamps are generally less expensive than metal halide lamps and can be distinguished from metal halide because of their golden glow. Colors other than white or gold can be achieved by adding lenses to the fixtures. Timers and dimmers can also be added to the lighting systems to allow for variations in the bridge illumination during holidays or special local events such as boat parades. Upcoming Florida bridge projects that include decorative lighting are the Broadway Bridge in Daytona Beach and the 17 th Street Bridge in Ft. Existing bridges, such as the MacArthur Causeway Bridge in Miami, are being retrofitted with lighting.
