PROJECT DETAILS
I-74 Bridge
Iowa, Mississippi, United States
Installed Products
After more than a decade of planning and collaboration, the I-74 Bridge, which spans the Mississippi River, has emerged as a striking beacon of civic pride and connectivity for the Quad Cities. Designed with signature double basket-handle arches, the bridge comes alive at night through a dynamic lighting design that features over 25 programmed scenes celebrating local events, holidays, and the changing seasons.
At the heart of the illumination strategy are Lumenpulse's Lumenbeam and Lumenfacade luminaires, selected for their precision optics, rugged performance, and architectural integration. Lumenbeam fixtures provide powerful uplight to emphasise the verticality and elegance of the arch structures, while Lumenfacade luminaires follow the graceful lines of the suspension cables and end beams, illuminating the arches from top to base. The result is a layered lighting composition that transforms the structure into a vibrant icon after dark.
Designed to endure Iowa's extreme weather, high floodplain conditions, and long-term use, the Lumenpulse system was specified with high durability, corrosion-resistant finishes, and minimized maintenance needs. Mounting solutions were engineered in coordination with the bridge's steel deck fabrication—ensuring seamless installation and future access for servicing.
Along the pedestrian path, the experience is enhanced with a glowing overlook and illuminated glass oculus, offering travellers a moment of calm amid the movement. The bridge's "Identity Element" columns creatively use reflective highway sign material to distribute light from a single Lumenbeam at each base, reinforcing a sense of storytelling through lighting.
Today, the I-74 Bridge stands as more than a means of crossing—it is a bold, illuminated expression of community, engineering, and design excellence.
