Light bridge

The Energy Bridge is one of the many mysterious technologies seen on Installation 04. The Forerunners built Halo with many interesting and unknown technologies, one of which is the energy bridge. It is a bridge comprised of "solid" energy, which can support an enormous amount of weight. The bridge works when a switch triggers increased photonic activity, and the photons displace the air around the light path. When this happens, the light becomes coherent and solid.
