A "trolley" system for cranes

(Satellite)

I wonder if this project is for a new causeway for the new Bonner Bridge. The photos below show a Manitowoc 2250 being built on a platform that runs on rails held up by piles. It looks like the assist crane is also a 2250. A comment by Todd Rennix indicates that six cranes will be on this job when it is up to speed.

Judging by the houses in the background in the third and fourth photo, I assume this work is on and/or along the Outer Banks. (It looks like those houses survived their hurricane better than the houses along the Florida Panhandle.) a trolley system is probably being built to minimize the impact of the crane work on the land. It might be hard to build a road strong enough for the cranes to travel on. Even if they could economically build a strong road, the road would destroy a lot of land. The piles holding up the trolley rails have the advantage that they can go as deep as needed to provide a good foundation and they leave a small impact on the land after they are removed.

It looks like a comparable system is being used to build a causeway in Austrailia.
