|June 2014 (37.69736, -122.04098) Old Dublin Road Bridge|
In the next photo we can see the other arch bridge in the distance crossing the creek. I walked over to it but I couldn't get close enough to determine what road (if any) it carried. My best guess is that it's a long culvert carrying I-580 over the creek.
