The only differeces that I could find between the two bridges is that this one has the steel girder painted blue-grey, while the other bridge has the girders painted red-brown. Each bridge has 4 bridge plates, two for each county, and they are shown in final photo below.
The widening of the pier is visiable in the 2nd photo from the bottom. Notice that there is a small round pier at the far end of this pier, and the concrete pier cap is independent of the original H-shaped pier. This additional pier is used to support one additional bridge girder.
