A bizarre rarity for sure Art!
Pinned Warrens were not plentiful. It was found that excessive wear could occur on the pins due to the natural forces of a live load crossing. The building of Warren through trusses all but ceased until riveting and gusset plates gave them a new lease on life.
The design, weather built as an experiment on CBW's part or at the bequest of local officials exhibits some oddities that I will be surprised if we find repeated elsewhere!
The bridge lasted until 1926 when it was replaced by a concrete arch structure.
*And yes Art, I did blow the photo up to confirm CBW! ;-p
At first glance in an old fuzzy pic the plaque also kind of resembles a Groton design (In my humble opinion) and the portal bracing was certainly more in line with some of their spans. Groton did sprinkle an occasional bridge here and there, so the possibility that they could have snuck in an stole a contract (especially given the internal problems I believe were starting to fester at the hometown firm) was not out of the question. I am indeed glad it was a CBW and it just adds another chapter to their unique story!
If June 1888 bid opening is accurate, this is one of the, if not the last Morrison bridge. It would be made by Columbia Bridge Co.
Bids were opened June 1888; cannot find documentation of the builder
Have you ever seen a CBW / Morrison product like this? And yes, that is the traditional CBW / CBCo. plaque on top of the lattice portal!
Now if Melissa can find info on this one...
