The Pontoon Bridge is a Structure in the Primitive+-DLC of ARK: Survival Evolved. The Pontoon Bridge is a foundation that can be placed in the water. Foundations are required to build any kind of housing/storage structure.
A Pontoon Bridge can be placed in the water but must not be touching the ground. Once the first Pontoon Bridge is placed, subsequent Pontoon Bridges can snap into place along the first one, allowing them to line up, provided that there is adequate room and open water to do so.
A foundation provides the structural support to allow the placement of walls, ceilings, and other such objects, but only when the Pontoon Bridge is directly underneath them. It also supports up to two ceilings in any direction on the x and y-axis, and up to 1 ceiling diagonally. However, the ceilings on the far end will not support walls.
If a foundation is destroyed, any building pieces that rely on it for support will be destroyed as well. If it was destroyed via the demolish option, no resources will be refunded for these extra building pieces.
The Pontoon Bridge can connect to other foundations in the water.
By lowering floor foundations with pillars on a raft; you can connect Pontoon Bridge to the Raft.
