Not to parade on the quality of this map, but the gaps between islands are far too large to build
rope bridges. Alternative designs are probably possible, however they would definitely not be able to be created in any reasonable time frame. (I didn't bother to try)

Admittedly, scale is hard to see in the editor.
In the future, I recommend testing the map many times in the creation process. While it is possible to repair this minor spacing error even with the map finished, it will take a lot of effort, undoubtedly much more than if you had caught the problem early.
