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 E 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 all ships require the bridge to be opened to pass. If a ship is in the way of the raised drawbridge it cannot be lowered until the ship is moved or destroyed. Ships that linger under bridges start taking damage after 30 seconds and die in less than 5 minutes. If the drawbridge is destroyed no vehicle or ship can pass through except submerged Submarines.
If structures are built on the movable parts of drawbridges, they will be instantly destroyed when the bridge is opened.
Two Tier Bridge
The Two Tier Bridge has an infantry path on either side of the bridge.
Shippables (like Emplacements) can't be placed on the moving part of the bridge nor or on the ramp but there's a small area at the top of the ramp that allows them.
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.
Shippables (like Emplacements) can't be placed on the moving part of the bridge but everywhere else allows them.
When destroyed infantry can still cross it.
Train Bridge
A bridge that comes with a Railway Track to allow large Trains to cross rivers.
