SPF:architects' new pedestrian bridge, named "Rainbow Bridge", is now open to the public of Long Beach, CA. The bridge provides a connection between Long Beach's Convention Center and Performing Arts Center. 

Previously, moving between these spaces required navigating loading docs and HVAC equipment on a stretch of the Seaside Way. Initially conceived of as a simple elevated sidewalk, the walkway developed into a much fuller project. Visitors can now not only easily connect between these two spaces, they can also enjoy an architectural experience along the way. 

The finished project is a 600-foot bridge consisting of 76 custom-welded bent-steel ribs framing the top, and approximately 1,200 cubic yards of poured-in-place concrete shaping the base. The bridge canopy features 3,500 color-changing LED node lights, which can be programmed and synched to music to create different effects.

SPF:a worked closely with Carl Stahl Architektur to create the custom, three-piece, stainless steel node clip that allows for the bridge’s LED wiring to attach to the canopy. The unique design also allows for ease of installation and replacement flexibility. Power and drainage for the walkway plantings have been hidden within the concrete spine of the bridge.

The overall design is heavily influenced by its beach surroundings with structural elements such as its hull-like formation and net-like cables. Rainbow Bridge has already received the Honor Award from the American Council of Engineering Companies of California for Engineering Excellence.
