Groton Iron Bridge Co. Builders
Groton, N.Y.

Groton Iron Bridge Company was incorporated in 1877. It was the successor to the Groton Bridge and Manufacturing Company, an outgrowth of Groton Iron Works, which was established in 1849. In the next twenty-two years, they became one of the major bridge builders of the northeast before being taken over by J.P. Morgan's American Bridge Company in 1899, from which came the U.S. Steel Company in 1901.

The two bridge signs below were from a bridge near Cooperstown, NY. and are 12" X 19".

The Bridge Street Bridge

Located in Portland, MI is a rare two-span metal through truss, with two spans 100 feet in length, features decorative treatment on the end posts. The overhead bridge sign is dated 1890 and is the oldest known surviving example of a truss bridge built in Michigan by the Groton Bridge and Manufacturing Company of Groton, New York.

Found at an Auction

The sign was purchased at an a public auction in Sullivan, IL. I bought it for particular reason, other than I am always on the lookout for something different. I have no idea where it came from. A friend is making an arch type support for the sign. The original bolts are still with it so that it what I will mount it to. For the moment I will be putting it at the entrance to my flower bed, unless I find it will look better elsewhere
