Notes:
It's obvious from the pictures that I found this one at night.  My Wife & I were looking for a nearby Geocache and I had parked near the end of the bridge.  After we found the cache, a quick look on the bridge deck turned up GU1766.  I'll have to return during thr day to get better pictures of the setting and the surrounding area.
