Protected bridges, yes they take more time, but they're worth it. It's a safe place where you can't get shot off.
Also, even though I made a post to help stop camping, I will say this: Any camper can be beaten with enough patience. You just have to wait them out and buy backup gear. Yes, campers can be annoying, but it's easy to just camp back. Yes, camping is bad, but if you can't leave your island without getting killed, don't leave. Let the campers come to you. My point is, campers are annoying but able to be dealt with.
