Delaware Avenue Trail - Black Bridge

Speaking of obscure builders, I’m sure some have seen this document, but I figure I will post it anyways. It lists histories of many prominent bridge builders and the companies they worked for. I thought it was a fascinating read:

I believe that firm was purchased by John Alden and Moritz Lassig after Thomas Leighton (Leighton Bridge & Iron Works) retired. Alden and Lassig split in 1886, and Alden kept the works until 1900, when it was purchased by American Bridge.

I think this is the most likely builder, especially since Charles Hilton (who had worked on the Quadrangular design for railroad use) was with Leighton, and the design was continued by both Alden and Lassig.

I'm certain it wasn't the Rochester Bridge Company out of Indiana... But perhaps it was this more obscure NY firm:

Could the builder possibly involve the word “Rochester”? Otherwise, I would be at a loss..
