It looks like the original plaque was removed and replaced with the 1905 plaque. I have seen a lot of these from bridge relocation projects. They certainly don't merit the same recognition as the original builder, and should have put it in another location.
This is a pin-connected lenticular pony truss constructed by the Berlin Iron Bridge Company of East Berlin, Connecticut. It contains their trademark railing design on the sidewalk. The NBI given 1905 date is incorrect, because this company was absorbed by the American Bridge Company in 1900. 1905 may refer to a rehab or relocation date.
Based on the photo added, this is not a lenticular and is just a parker truss... and also has had load-bearing stringers added under it.
