I had no idea that this bridge once contained a couple of Marsh arch spans. I do remember the train platforms. I became curious about them when I drove over the old bridge on several occasions. I drove over the new bridge a couple weeks ago for the first time.

Now that the new bridge is in place, I don't know how much longer the deck truss to the south will remain.
