Anyone with some insight on what that might add to the tab for the bridge? I'm assuming if/when they start construction on the tunnel, that would be completely shut down and all rail traffic would have to go through Port Huron. That's got to take an economic toll.
I don't know about the bridge structure itself, but acquiring the land and building rail approaches to the bridge at a shallow enough gradient for trains to handle without extra power would probably be the prohibitive part.
