Description 

This bridge has been flagged for demolition and replacement in late summer 2018 by TNDOT.

It is unusual for a bridge to be flagged for demolition by a state agency just months before the demolition is planned. It is even more unusual and insane that the reason given for demolition is outright wrong. The reason given is that this bridge is “like the I-35W Bridge that collapsed in Minneapolis”.

First of all, if properly maintained, bridges like the I-35W Bridge are not at risk. Secondly, this bridge isn’t even that similar to the I-35W Bridge.

It appears that TNDOT is just looking for an excuse to demolish and replace this beautiful deck truss bridge with a mundane concrete and steel stringer bridge like they already did in 2002 with the nearby Swanns Memorial Bridge.

Well, this bridge is safe... at least for now. The planned demolition of this bridge over the summer was blocked/halted/postponed/whatever, meaning the bridge is still intact. However, it’s days are numbered as construction of the substructure for a replacement bridge is slated to begin in March or April 2019 (this coming spring). The design of the replacement bridge is either going to be a haunched girder or a modern truss of somesort, so at least they’re not tearing this down and building a UCEB, but whatever final design they choose will be worse than the current bridge, especially given the hideous replacement of the Swann Bridge that crosses parallel to this bridge, which is a UCEB.

Current plans appear to be to replace this bridge with a “haunched girder bridge” that apparently will be “like the Sam Rayburn Bridge over the Clinch River”, which is also on I-40. However, as we saw with the Hulton Bridge in PA, and the Fort Stueben Bridge in WV/OH, even an “attractive” girder bridge or cable-stayed bridge, while better than an outright UCEB, still cannot replace the geometric beauty of an historic truss bridge.

I can certainly say that I'm not surprised--TDOT should be renamed TennDOT, since it rhymes with PennDOT, and their level of care for their historic bridges are right on par with each other. They are on a crusade to destroy every last truss bridge in the state, and at the rate they're moving, it will be a very short time before they accomplish their goal. It's a good thing that Tennessee has plenty of natural beauty, otherwise there would be little reason to visit.
