Picture History 

Written by Calvin Sneed

These pictures were taken in 1974, as a northbound train approached. The steel bridge has been painted several times since.
I visited again in 2015 and found the bridge in need of painting again. The railroad and this bridge gets a lot of traffic since CSX closed its companion parallel north-south route between Athens, Alabama and Brentwood, TN.

Thank you gentlemen. Bridge type corrected.

I agree as well; definitely a Warren.

Looks like a Warren with verticals to me... note that the little diagonals at the end panels are not a subdivision of panel, they are called "crash bars" and designed to reinforce the end posts.

Looks like a Warren truss with all verticals and end sub-panels. Anyone else concur before I correct it?
