I have thought of 2 ways to get the concrete back. One is to use power buggies (
Quick ride-on concrete buggy and material mover - The Power Buggy). They have a capacity of about 3/4 yard, so this would mean about 50 trips across bridge. Bridge is about 1/8 mile from build site. Another would be to get a loader (small enough to fit over bridge) with a big bucket to move the concrete. I will be hiring a concrete guy to do this, but I just wanted to have this thought out before talking to them.
Any thoughts? Better ideas? Helicopter transport?
Thanks!
