At a recent special ceremony on The Big Four Bridge, Louisville, Ky. Mayor Greg Fischer flipped the switch to reveal a new LED lighting system from Philips. The new dynamic color-changing lighting system, a shining example of public-private partnership, transforms the popular daytime destination into a lively nighttime art piece and backdrop for waterfront events. The project delivers on Mayor Fischer’s six-year plan to create a clean, green, inclusive environment through the use of innovative, energy-efficient LED technology.  The addition of the lighting further cements the bridge as an iconic symbol of Louisville and a reflection of the vibrant community that surrounds it.
