1992 NBI shows a 1927 T-Beam, so this one has probably been gone 90+ years.

Tony,

I've seen four panel through trusses as well but I'd expect them in railroad use not for wagons. The other known Keystone Column short span bridges are both ponys.

I'll throw one more thing at you. The ends of the bridge definitely look like Keystone. But, to me, the upper chord joint at the midpoint seems non-standard for a Keystone product. Usually the upper chord is not a Keystone Column and the joint blocks are more subtle. In this case, joint block is bulky and extends beyond the upper plane of the top chord. I've seen this with Phoenix Columns and cast iron top chords. Could the top chord consist of Keystone Columns or be cast iron?

Regards,

Art S.

PS. When you maximized the image in the link, did you notice the guy riding the unicorn on the bridge :^)

Doubt it's recycled considering the cut stone substructure it sits upon. 4-panel through's were pretty uncommon but I've seen a handful. Likely wrought iron with cast fittings.

Zooming in on the picture in the link - almost certainly looks like a Keystone product but still is very short and stout for such a short road span. Its also quite late for Keystone Columns (or cast iron). Very cool bridge, would love to learn the backstory.

Regards,

Art S.

Thanks to both on the photos. I was wondering if it was cast iron, Keystone or Phoenix Columns. The magnified image does have me leaning toward Keystone as well but does anyone have confirmation.

Very short bridge for a through truss. Maybe recycled?

Regards,

Art S.

PS. Its a Pratt Through truss.

Neat little 4-panel Keystone column Pratt through truss!
