I would hold it notable based on the bridge it replaced. Not saying every concrete bridge is notable for replacing a historic bridge, but due to the fact this one replaced a bridge that was part of a major collapse, I believe makes it notable.
I agree this is a very "notable" structure. The bridge may be modern and the structural design may be a bit boring, but the span still invokes interesting discussion on the state of our bridge maintenance.
The website says, "Bridgehunter.com is a database of historic or notable bridges in the United States, past and present." I think this qualifies as "notable." There are many modern bridges on this website. Here's an interesting one built in 1995:
It's still modern and doesn't belong on HISTORIC Bridges of the United States
Now this is a real work of art for a modern bridge.
