This isn't the first time I've heard of the tunnel being removed either. I guess with the salt air that tunnel/bridge probably wasn't that much better off than the Sara Long was. If you've got the crew, machinery and manpower already there, why not get rid of it now? It probably kept cost down by doing it now vs later and since it has no purpose, it make sense to eliminate it now before a possible safety hazard arises down the road.
It takes real skill to choke on air, fall up the stairs and trip over nothing. I have those skills.
