What I do not understand is that this bridge is not listed on the NBI database. The road is still very much active, in fact, I drove across this bridge when I was in NM in 2009. The bridge is long enough to be on the NBI. So, if anyone can explain this, I would be grateful. I imagine that this bridge was built in the late 20's or early 30's since this is an original route of US 66.
