According to Bing Map, there appears to be a pony truss in light colors that exists, but I'm not sure what the truss type is. Your best best is to check it out in person. It's on Iris Ave.

Hope this helps.

The early 90s NBI is known to have extremely wayward GPS coordinates

This bridge doesn't seem to exist, at least at this location. It could possibly reference a crossing just to the east, but it is not a pony truss. Does anyone have any more info on it or should it be deleted?
