GE lamps bring amber color to historic Kentucky bridge
Colored underpass lighting and LED accent lighting from GE has been chosen to illuminate the historic George Rogers Clark Memorial Bridge that crosses the Ohio River.

Leni Schwendinger of Light Projects Ltd, the lighting designer, chose to light the massive I-beam girders and bridge surface using programmed cast lighting. Schwendinger used 54W GE Ecolux Starcoat T5 fluorescent tube lighting for the bridge underside and wash lighting. The luminaires incorporate weatherized tubes and colored glass to create crimson and gold hues. A Digital Addressable Lighting Interface (DALI) control system was adapted for exterior use and complex lighting sequences.

GE Protected ConstantColor PulseArc Ceramic Metal Halide (CMH) ED17 and ConstantColor PulseArc CMH T6 lamps were pole- or clamp-mounted to provide street and bridge column lighting. Crimson-colored ConstantColor PulseArc CMH ED17 lamps served as bridge coffer accent lighting.
“While the Second Street Bridge project embodied a very unusual application for fluorescent tube lighting, these lamps worked perfectly,” Schwendinger reflected. “The underside of the bridge started as a dark, uninviting space and has been utterly and completely transformed into a meeting ground for events.”
Located near the City’s recently revitalized “Whiskey Row” that once served as the center of Louisville bourbon production, the Second Street Bridge was repainted to a cream color, which, when illuminated by its new crimson- and gold-colored fluorescent lighting, takes on the amber color of the bourbon for which Kentucky is famous. The bridge’s appearance was also designed to be reminiscent of a sunset magnified by the Ohio River.
The public space below the Second Street Bridge was opened in October 2010, on budget.
