This iconic bridge sits near the mouth of the Oconto River, and contains many historic details
Originally built in late 1903 and erected in 1904, the main swing span of this bridge was once capable of turning. Although it has not for many years, it still has all the machinery necessary to operate.
In 1911, at least the south through girder span was added to the bridge. It is unknown if the north I-Beam span was added at the same time, although it seems likely.
The bridge rests on massive stone substructures.
Unfortunately, the perfectly sunny day turned cloudy right before I got here.
Overall, the bridge looks to be in great condition. The author has rated the bridge with moderate significance, because of the common design turned into a swing bridge.
The photo above is an overview.
