The Camelback spans here are also not K-Parker spans.
The state of Tennessee did not have any K-Parker spans..
Back in the 20's and 30's, the state built hybrids utilizing the K-span concept to get the span length engineers wanted, but the bridges are hybrids only, not genuine K-spans.
You're correct.. they are not ponies.. my bad. T-DOT Region 1's Engineer in Charge of Bridges, says the two approach spans on either end are Through Camelback, Subdivided Warren Trusses. I sent him pictures and requested clarification.
The approach spans on this bridge are unique. They are not ponies as stated in the text, but are indeed through trusses. They have an arched top-chord, but with only 4 slopes. A Camelback has 5 and a Parker 6 or more. Not sure what you would classify these spans as.
