What would the next step be please? Pure logic, I don't want to make assumptions and work through until it fails.

I see one move, but I'm not sure it will help you progress much farther.

Look at the 3 in the 3rd row up from the bottom. It needs 2 more links. Only 1 link can go to the 2 above. Therefore, at least 1 link must go to the 2 to the right.

Thanks, that helped. I completed it but had to resort to trying assumptions.

You need to use the 3rd rule: "When completed, all bridges are interconnected enabling passage from any island to another". There are several trivial steps in the puzzle if you use this rule. For example, the 4 on the bottom row. If you connect its last bridge to the right, you will get an isolated segment. Therefore the last bridge of the 4 on the bottom row should go upwards.

Thanks, Dave

Also there are two 2s that are adjacent - both bridges can't connect them, therefore at least one bridge must go elsewhere.
