A revolutionary breakthrough in bridge design.
With clear spans of up to 400', Big R’s Tunable Bridge is a structural hybrid that’s long on possibilities and short on costs. The Tunable Bridge combines the physics of a tied arch with any standard steel truss system or girder superstructure.
The bridge features an innovative adjustable structural system to balance the live and dead loads between the arches and trusses. With no fracture critical members, this redundant stress sharing system increases safety and allows for lighter, lower-cost material and longer, more-graceful designs.
