Bridge (structure)

For the command center of a starship, see Bridge. A bridge is a structure built to span a physical obstacle such as a body of water, valley, or road, for the purpose of providing passage over the obstacle. More advanced version of a bridge include the energy bridge and the gravity conveyor.

Forerunner
There are multiple bridges that span across canyons on the Halo installations. There are different forms of bridges depending on the location and functionality. The Forerunners built various types of bridges to span large canyons. Many such bridges designed to span large canyons are supported by energy cables, similar to the supports of a truss arch bridge, attached to structures on each canyon's hedges.

Forerunner bridges appear in a diversity of designs. Different bridges have been observed as having one, two or three levels. On Installation 04, many bridges featured two levels, with glass floors on both levels. The glass floors on the top level were breakable, allowing one to drop down to the bottom level of the causeway. The bottom levels glass floors featured impenetrable glass. There were also many structures on both levels of the bridge, which could serve as cover during combat.

In Halo: Combat Evolved, causeway-type bridges appear in the campaign levels Assault on the Control Room and Two Betrayals, and Gephyrophobia in multiplayer. In Halo 3, the multiplayer map Narrows is set on a type of causeway.

Energy bridges
Energy bridges are bridges made up of hard light.

In the Halo: Combat Evolved campaign, energy bridges are featured in the levels Halo and 343 Guilty Spark. In the campaign of Halo 3, they appear in the levels The Ark and The Covenant. They are also featured in several Halo Wars levels with a Forerunner setting, including Beachhead and Terminal Moraine.

Human
Bridges constructed by humans most often superficially similar to ones built using conventional engineering methods, although some are rather impressive in scale; an example of this is New Mombasa 105 East's enormous suspension bridge connecting Old Mombasa to New Mombasa.

Covenant
The Covenant employ various forms of bridges, ranging from physical structures to more exotic walkways and platforms based on energy fields. These include gravity conveyors which use an anti-gravity field to carry individuals to the other side.
