Bridge Documentation

Despite its short length, this bridge is significant as an old 1881 example of a wrought iron bridge built by the King Bridge Company, and important and prolific bridge builder during the pin-connected truss bridge era. The bridge appears to have had its original deck stringers replaced with larger beams that actually bear the live load, with the trusses only supporting themselves.

This is one of the most unique King Bridge Company Pratt trusses in existence today because despite being a Pratt truss, some of the company's bowstring truss details were carried over to this Pratt truss design. That includes the tapered hip verticals as well as the connection design for the outer portion of those hip verticals to the floorbeam, via threaded rod and steel strap. The bridge also uses rare massive square head bolts for the top chord pins rather than a standard threaded rod with nuts at each end. This design of pin is found on a limited number of King bridges.

This attractive historic bridge is located in an excellent place, in a park setting within view of the beautiful Buttermilk Falls.

When visited in 2007, the bridge, although closed to vehicular traffic, retained modern Armco guardrail on the bridge. A revisit to the bridge by Marc Scotti revealed that the bridge had been redone with an eye toward its current pedestrian use. Which basically means hideous wooden bicycle code height railing was added to the bridge, all but completely hiding these unique historic trusses from all views except beside the bridge. For a small pony truss of this type, the use of a wire cable railing would have been a better choice
