Conway Bridge
Posted June 11, 2010, by Calvin Sneed (us43137415 [at] yahoo [dot] com)

I have identified 30 dual ribbed spandrel arch bridges in Tennessee, 5 of them eligible for the National Register of Historic Places. I have even located a 7-ribbed, spandrel arch bridge. I don't know if they're open or closed..my records don't show.

As I have found, the Conway (Nolichucky River) Bridge is the only dual-ribbed closed spandrel arch bridge that crosses a river in Tennessee. It's the only one of the 30 with 4 spans, and there is one with 5 spans.

The question is, are the rest of them still standing, and if so, are they open or closed spandrel? They were all built in the early 1920's. That is something I am researching, and will report back with pictures.

I've added a new design category called "Ribbed closed-spandrel arch." I was going to call it "dual-ribbed", but decided to leave it open in case somebody finds a three- or four-ribbed example.

Yes, the Georgia example certainly appears to be of the same design.

I believe this bridge in Georgia would also be considered a dual rib closed spandrel arch.

Interesting. I have seen many dual ribbed open-spandrel arches, but this is the first dual ribbed closed spandrel I have encountered. Perhaps this was a localized design.

They're not curved tee beams. T-DOT officially says all the spans are dual ribbed arches. A magnificent, elegant bridge in a quiet, tranquil setting.

Initially this bridge does resemble a deck arch. However, it might be better classified as a curved T-beam. Anybody have any thoughts on this?
