Period photos, especially along the Tennessee River and Chickamauga Creek, show remains of bridges and some that were rebuilt. Although slight alterations may have existed, I am more interested in the reamins as they are more likely to be most prototypical.
The Howe Truss pictured above, which crosses Chickamauga Creek, is my template for a bridge I chose to model.
Researching bridge construction was done through photographs primarily. One find was that bridges were made with 30' timber lengths. I estimated (guesstimated) that these bridge sections, in general, were approximately 90'. This offered the opportunity for a bridge model long enough for that dramatic and more authentic appearance. The model below was built to accomodate three 90' sections spanning 270 scale feet.
At this stage the bridge is completed, abutments have been placed and we are now contouring the river's landscape. Brian Kammerer has been working on the backdrop and has included Lookout Mountain, a most prominent land feature distinguishing the Chattanooga area. I will be sure to include photos of Lookout Mtn. in a future posting.
The following photos are described below the picture.
Stay tuned for more posts as we reach completion.
