I have spent the last 3 days playing with the dimensions of the bridge piers. They won't end up 1:48 because the bridge is just too darn big, but they will be proportional to the structure. That's my thinking right now. Here are a few photos and my drawings.
This photo is taken from the Ohio side of the river. Upstream is to the left; downstream to the right. Interestingly enough, there are no debris deflectors on the bridge.

Here's a closer view of the top of the pier. Each of the "rings" in the pier are 3' high and made of poured concrete. You can get a decent look at the leftmost bridge foot.

This is a closer view of the south end of the pier. You can see the handrails pretty clearly. I caught the navigational warning beacon flashing red. The Ohio River sees a significant amount of tow boat / barge traffic.

I will use it to make a pink foam "positive" of half of the pier (split lengthwise down the middle). The foam will get sealed with joint compound, sanded, and lines for the rings will be scribed. Then a mold will be made. Pier halves will be cast. A groove to hold the wires for the slow flashing red LED lights will be cut. The halves will be then be glued together to form completed piers. A sand color concrete paint will be used. The piers are surprisingly complicated.

Now why didn't I think of that?
