There is a jewel on the Trackside Guide part of this Forum… Nanaimo 73 has authored, and with help from some others has coordinated a really informative piece of documentation on the railroad crossings of the Mississippi River[ both upper river, and lower river]. I had skimmed it some time back, and it was interesting then, but it has grown to be quite a document; if you have not visited it, it truly bears reading and enjoying.
Thanks, Dale, and the other contributers that have added the photos and information to your project.
Good Job[tup][tup]
