Upper Paris Bridge

From the Iowa DOT website:

This unusual Whipple truss spans the Wapsipinicon River in northern Linn County. It was built in 1879 by the Ohio-based Canton Wrought Iron Bridge Company for $3,400. The timber and stone substructure was constructed by Cloyston and Wood for $1564.72. The bridge is a fairly rare example of a double-intersection Pratt truss, also known as a "Whipple" truss, which was first developed by Squire Whipple, an early American engineer, in 1847. Additional construction documentation for this long-span truss do not exist in county records. Barring a minor replacement, the aesthetically striking Upper Paris Bridge carries intermittent vehicular traffic in its rural setting. The Upper Paris Bridge is distinguished as a well-preserved, large-scale example of a Whipple truss. Basically a Pratt with diagonals that extent over two panels, the Whipple truss was seldom employed for wagon trusses in the state. Few were ever erected and fewer yet remain today. This structure is one of only eight pin-connected Whipple through trusses remaining in Iowa and is the longest of eight. For its exceeding rare use of wrought iron components, its rare truss configuration, and its overall length, the Upper Paris Bridge is a structurally significant wagon crossing in Iowa.

Brian I am very glad you like this shot. I wanted to get a better look at this bridge but kids were jumping off into the river and I figured I can always come back. Tried something different. Many thanks for the L4&F2. Best wishes, Dave.
