Pushing the limits of bridge design and demonstrating the potential of glass as a structural material, the Luminous Glass Bridge guides the pedestrians along (or against) the river’s current. The sun hitting the surface of the water reflects the surface of the moving water up onto the underside of the translucent glass projection surface which doubles as the bridge deck. This glass deck, a series of post-tensioned glass planks, is supported at each end by two abutments cantilevered from opposite shores approximately 80 feet from each other.
