You mean retractable draw bridges? Might be worth checking out Falsebook for that.http://forums.bukkit.org/threads/me...kkit-85-ics-gates-minecarts-mc1-2-3-2066.7227
the plugin is portecoulissante (for vertical ones) and retractable bridge (for bridge, obvisously). from the same author. and it works flawlessly.
dont think this plugins need any updates. they are 1.1R5 compliant, they probably works with any 1.2.X builds.
