I first saw this bridge in about 1970, definitely before Hurricane Agnes in 1972. At that time I was exploring using a fairly detailed county map. I approached from the Anne Arundel County (east) side. Even then, the road bed from the intersection to the bridge was completely overgrown, the paving gone, and a mound of earth blocking the path. At that time, the bridge was lying collapsed in the Patuxent River. Sometime in the middle or early 1960ís it collapsed under the weight of a truck, probably a gravel or sand truck. Sometime, after 1980 I think, the bridge was restored and used for fishing. The deck at the time of the collapse was probably wood planks with macadam cover.
never mind - I realize it's a Pratt pony truss, not a through truss. I'm changing the design description back to what it was.
The Maryland State Archives link that I posted confirms those are Phoenix columns, and that the bridge was likely built by Dean and Westwood around 1890. The Maryland State Archives document describes the bridge as a Pratt through truss, but the Bridgehunter page initially said Pratt pony truss. I cannot tell which one it is, so I changed it to Pratt through truss, since that's how the state describes it. The State Archives document has a lot more interesting history about the bridge and this specific site.
Yes, this bridge is composed of Phoenix columns on the top chord and end posts. It was likely built ca. 1885 by Dean and Westbrook of New York, New York. My reasoning for that is because it is nearly identical to this bridge I documented in New Jersey: http://www.historicbridges.org/bridges/browser/?bridgebrowse...
Looks like the entire upper chord is composed of Phoenix columns...interesting!
Sure looks like Phoenix columns on the end. This would make this a very old bridge. Pre-1900 I think.
Are those phoenix Columns I spy?
Maryland may well have another hidden gem in this bridge.
Scrolling through this post you will come upon some nice shots of this bridge:
