Bridge

Description
Bridges are World structures that allow players to cross over rivers, as players cannot swim across rivers. There are multiple types of bridges. The bridge types listed below can be destroyed and they can be rebuilt with a hammer and Basic Materials by pressing  next to the bridge husk (with hammer in Upgrade Mode). Every other bridge in the game is indestructible.

Wooden Bridge
Wooden Bridges are weaker than Stone Bridges and can only support foot troops across. The bridge is too narrow to fit most vehicles, but it can fit an Armored Car or a Light Utility Vehicle.

When destroyed infantry cannot cross it.

Stone Bridge
The Stone Bridge is tougher than the wooden bridge and is wide enough to accommodate one vehicle on the bridge.

When destroyed infantry cannot cross it.

Drawbridges
Drawbridges have movable parts that can be raised to let ships pass through. In order to raise the drawbridge, a player must activate both switches located on each side of the drawbridge. To lower the drawbridge, only one of the two switches must be deactivated by a player. If a player is driving any type of boat or ship they can simply press  to open or close the bridge while close to it.

Motorboats, Landing APCs, and amphibious LUVs can pass under drawbridges even when not raised, but Barges, Freighters, Gunboats and Landing Ships require the bridge to be opened to pass. If a large ship is in the way of the raised drawbridge it cannot be lowered until the ship is moved or destroyed. If the drawbridge is destroyed no vehicle or ship can pass through (except small wooden drawbridge).

If destroyed, the structure must be rebuilt with a hammer.

Wooden Drawbridge
The Wooden Drawbridge is strictly a footbridge; it is too narrow to fit most vehicles. An Armored Car or Light Utility Vehicle is skinny enough to fit, however. It's the only drawbridge that let ships pass through it when destroyed.

When destroyed infantry cannot cross it.

Reinforced Drawbridge
The Reinforced drawbridge is tougher than the wooden drawbridge. Players can climb on the arches on the sides of the bridge. Ladders on each side of the bridge help people that are in the water get back on the bridge.

When destroyed infantry can still cross it.

Two Tier Bridge
The Two Tier Bridge has an infantry path on either side of the bridge.

When destroyed infantry can still cross it.

Double Bridge
The Double Bridge is wide enough for two lanes of vehicle traffic. Ladders on each side of the bridge help people that are in the water get back on the bridge.

When destroyed infantry can still cross it.

Long Bridge
The Long Bridges are designed to cover large gaps and are two lanes wide. Beside their main drawbridge, they possess four additional waterway arches that are indestructible. Two of those are high enough to let Landing APCs, amphibious LUVs, and motorboats pass through while the other two can only let motorboats through. The long bridge doesn't have ladders but stairs and dock for infantry on each side.

When destroyed infantry can still cross it.
