John is probably right. Granted, this bridge looks far nicer than a modern slab, but if the 2004 date is correct, then we can be sure it is a ConSpan. At first glance, it looks like nothing special, but perhaps some locals might know about any significance that I do not.

I guess our webmaster can decide if it is worthy of being on his website.

Am I missing something? This is the 28th most voted for bridge on BridgeHunter and the average vote rating visitors have given it is about the same as that for the Golden Gate Bridge. It just looks like a modern pre-fab ConSpan style bridge to me. Construction date is listed as 2004. Is there more to this bridge than the date and photos would suggest?
