Ever wanted to build a Sea Bridge to allow land units to cross over coastal water plots to a nearby island? Now you can! The Sea Bridge requires Physics and a coastal plot that is between two land plots. A workboat will take several turns to build a Sea Bridge and will be consumed. The SDK change files are included and should be an easy merge into your own special mod. Version 1.0 provides the ability to chose the appropriate graphic for the bridge direction. The improvement now increases commerce.
