Not my idea but rather a friend of mine Mikehunt. He was wondering that with how nice the wood bridges look, why can't we have an option to build wooden docks, or any other material that is allowed for regular bridges. This would be a nice alternative to just dumping crates of dirt into the water to build a pier type structure. I imagine you could use the mechanics already found in bridge construction and just have part of the survey/planning done with someone moored out in the water in a rowboat.
