Colorful LEDs highlight city landmark
Known as Illinois’ “Gem City,” Quincy remains a prominent river city with a population of more than 40,000. It relies on the Bayview Bridge for commerce, which also now contributes to the beauty of the city.
Built in 1986 to handle the westbound traffic on U.S. 24 over the Mississippi River, the Quincy Bayview Bridge is an early cable stay bridge, at least for the U.S. The bridge has 56 cables set up in four planes, with each plane having seven cables on each side of the 182-foot main towers. Each pair of cables supports a 60-foot-long by 6-foot-thick bridge deck section. The sections were unique at the time since they were a combination of prefabricated steel and precast concrete. Also unique was a new epoxy coating on the cables, which are now commonly found on more recent cable stayed bridges.
After almost 30 years, the city decided to bring the luster back to the Bayview Bridge through a new lighting project in August 2015. The criteria for the project was to find a lighting scheme that would highlight the architectural beauty of the bridge without creating maintenance issues and energy cost. Klinger Associates, P.C., Quincy, Ill., Brown Electrical Construction Company, Quincy, Ill., and Lighting Associates Inc., Webster Groves, Mo., worked together to develop a lighting program.
After a thorough investigation, Bayview is now highlighted by 78 Dyna Flood QA and eight Dyna Drum HO RGBA luminaires from Acclaim Lighting, located in Los Angeles.
Using proprietary quad-color technology, the system contains four colors – red, green, blue and amber – under a single lens. Because quad-color technology mixes the colors under the lens unlike traditional technology that color mixes outside of the lens, the system delivers precise color matching.
The system also features RGBA chips, beam and spread lens options and a lumen range of 9,000 to 17,232 at 5,500 K, along with an adjustable yoke with onboard 180-degree flip inverted digital control display for menu selections and addressing. Both Dyna Flood QA and Dyna Drum HO have an IP 66 wet-location rating. With a DMX-512 control system, each unit features an auto-switching, multi-voltage power supply, and an on-board touch-sensitive menu.
As a result, the lighting solution is energy efficient, easy to maintain, and meets government requirements. “The lighting provided an opportunity to get together, enjoy our riverfront and see the culmination of a vision that’s lasted for decades,” Quincy Mayor Kyle Moore says.
