The surface of a bridge can be [[Paving|paved]] (Excluding [[Rope bridge|rope bridges]] and [[Wood bridge|wooden bridges]]).
As with reinforced cave floors, this is accomplished first by activating [[mortar]] and using it to '''Prepare''' the surface of the bridge, then using the appropriate pavement material to pave the prepared tile. No diagonal (corner) paving is possible.
[[Pavement]] can be removed from [[bridges]] at any time using a [[crowbar]]
