Bridge (structure)

There are multiple bridges that span across canyons on the Halo installations. There are different forms of bridges. Some are held up by unknown energy beams.

Types of Bridges

• The bridges spanning across the canyons of Installation 04, as seen on the levels Assault on the Control Room, Two Betrayals, Ice Fields, and more primitive bridges like the ones in Halo (level of Halo CE), Infinity and Danger Canyon .
• The bridge in the Halo CE multiplayer map Gephyrophobia.
• The Energy Bridge seen in Halo CE (Halo) and Halo 3 (The Ark) Campaigns are made of solid light.
• The bridge in the Halo 3 multiplayer map Narrows.

Causeways

• Causeways are bridges built by the Forerunners, to span large canyons. They have so far been featured in the Halo: Combat Evolved campaign levels Assault on the Control Room and Two Betrayals. The multiplayer levels Gephyrophobia and Narrows takes place on top of these causeways.
• Unlike the energy bridges on Halo, causeways appear to be made of metal. They are supported by lighted cables attached to each canyon's hedges. They also have supports much like that of a Truss Arch Bridge.
• Causeways appear in a diversity of designs. Most commonly, the causeway will have two levels. They have also been observed with one level, or three levels. On Installation 04, the causeways featured two levels, with glass floors on both levels. The glass floors on the top level were breakable, allowing you to drop down to the bottom level of the causeway. The bottom levels glass floors featured impenetrable glass. There are also many nooks and crannies where enemies can hide and take cover.
