Gravity bridge
From Halopedia, the Halo wiki
The Gravity conveyor[1] is a form of transport used by the Covenant. It consists of a horizontal anti-gravity field, often over a large gap, acting as a bridge. Whoever enters the anti-gravity field will immediately float up a few feet and be carried to the other side of the bridge at a high speed while suspended in a stasis field that prevents them from falling off. The Gravity conveyors are not always linear; curved ones appear as well.[2][3]
Appearances
Gravity conveyors are only encountered in Halo 2. They are seen in gameplay in the levels Template:Levelname and Template:Levelname. They are seen acting as bridges between the Valleys of Tears and in a large chamber above the Mausoleum of the Arbiter.[2][3]
