You don't have to locate the FEIS to find out the vertical clearance for the replacement North Portal bridge. Amtrak has been updating the nec.amtrak.com website and there is a fact sheet for the Portal bridge replacement (link to resource page with link to fact sheet PDF). The new bridge will have 53 feet of vertical clearance compared to 23 feet for the existing swing bridge. I expect part of what makes the replacement bridge project so expensive at close to $1 billion is that the project also includes long access ramps on either side of the new bridge for the higher elevation.With the new North Portal Bridge, what will be the vertical clearance for waterway traffic? Unless the bridge will be "way up there" (like the NJ Turnpike bridges), it looks like part of the plan is a reduction in clearances. If that's true, have the pertinent federal regulations been modified to allow it?
The question remains is how long will it take to get the funds in place to get started on building the North Portal bridge.
