Big Four Pedestrian Bridge

Louisville Waterfront Development Corporation

Louisville, Kentucky

The historic Big Four Bridge was originally built in 1895 by railway companies to transport goods across the Ohio River, and was in use until 1969, when the bridge was essentially decommissioned.  Through public-private partnership, the bridge was re-opened in 2013 as a pedestrian and bicycle path, reconnecting Louisville with Jefferson, Ind., and revitalizing the waterfront area.  Since its re-opening, the mile long bridge has seen an estimated 1 million visitors, making it a destination point for locals and travelers alike.

Building on the success of the project, Louisville’s Waterfront Development Corporation spearheaded an initiative to extend the bridge’s appeal into the evening hours with color-changing light. The system can display over 16 million colors and an endless array of patterns, creating a unique and inviting atmosphere for waterfront activities, and can enhance local elements such as concerts and fireworks, while also reflecting other special occasions. 

More than 1,400 Philips fixtures, mounted on both the interior and exterior of the bridge, and the software-based control system, which are managed by a software-based system, were installed and commissioned by Vincent Lighting Systems, the Kentucky-based systems integrator. Now pedestrians in the surrounding parks will have a dynamic lightshow to watch from dusk to 12:30 a.m. 

The new dynamic color-changing lighting system transformed the popular daytime destination into a lively nighttime art piece and backdrop for waterfront events and is likely to further boost tourism, benefiting the local economy.
