Paul:
looking through my files I find that Bridge 328A is the present bridge you see today, only the center span was retained. Some of my drawings have gone missing but it was built as 329A and in addition to the center span had 3 deck plate bridges and a tower between the 2 on the east end. Bridge 328B was a through plate girder bridge located about where the present row road cross's the Cimarron River. I had a picture of 328B from The Maxwell Collection and it had curved ends and masonry piers under each end. Unfortunately it has gone missing.
Hope this helps.
