Thanks for the comment Conster. I'm familiar with the puzzle you're talking about, but I wrote this one differently.
I think you'll find it a lot easier than the Hashiwokakero Bridge puzzles most are familiar with as there can be only 1 bridge in any given space (not 0, not 2) and some islands have no bridges. Think of it as a reverse Slitherlink of sorts.
Taking familiarity into account though, I think I'll try to make some of the traditional Hashi Bridge puzzles for future postings.

To follow up, I've decided to rename future puzzles like this to "Flip Flop Bridges" and use "Hashi Bridges" to describe the other puzzle type.
I'll also retag this one to keep the tagging in line.

Actually, Bridges has slightly more complicated rules: bridges can't cross, they need to be horizontal or vertical lines, more than 2 bridges between a pair of islands is not allowed, and (a rule this puzzle doesn't seem to have) all the islands need to be connected to each other by the bridges, forming a single group. Having multiple island groups makes this puzzle really hard.
