This bridge is one of the largest (as a two-span example) and most complete examples of a rather ornate bridge plan/design that Groton Bridge and Manufacturing Company of Groton, NY built that remain today. As such it is significant on a national level as a key example of the work of an important bridge company. The bridge has been listed as a Michigan Historic Civil Engineering Landmark.
So many times a road or street in a city was named Bridge Street, and so often today that name sounds exciting but usually reveals an ugly slab bridge. This is one Bridge Street that deserves its name. Portland has treated their historic bridges well, and has even brought more historic bridges into their city from the surrounding rural area. Portland is a very special city that has embraced historic truss bridges as the key attraction to their city in a way that no other city has. They have preserved more truss bridges than any other city in Michigan. The city logo actually includes an abstract rendition of the trusses of this bridge as the main part of the logo. Portland is a model city for showing the important potential that historic bridges have to enrich a community.
This bridge is a two-span pin connected Pratt through truss. It was built in 1890 by the Groton Bridge Company of Groton New York. Plaques remain on top of the latticed portal bracing on this bridge. Decorative finials adorn the end posts of this bridge. V-lacing is present on vertical members. The sway bracing has a bit of a arch shape, and is latticed. The metal grate deck and modern Armco car guardrails are not original. Original ornate railing on the cantilevered sidewalks remain on the bridge.
This bridge forms an attractive, historic, and exciting entry into the downtown of Portland. It does not provide an exit however, as it is one-way. With a two-way crossing nearby, this was a fine way to eliminate the "dangers" that people in charge of bridges often fret about with historic one-lane bridges.
