Bridge Documentation

This historic bridge is being replaced by TDOT and will be demolished!

This bridge is a mid-20th Century example of a riveted through truss. It was designed by the Army Corps of Engineers in conjunction with their project to build the Center Hill Dam. The new bridge was higher to accommodate the reservoir created by the dam.

The bridge retains good historic integrity aside from alteration of portal and sway bracing to increase vertical clearance.

As of 2014, a replacement bridge parallel to the historic bridge was being constructed. As expected of modern bridges, the replacement bridge is a stringer bridge and very uglu. The historic bridge is to be demolished afterwards, despite not being in bad condition.

The below historical photo was located online from a local newspaper with no information provided aside from a 1949 label, however it appears to show the newly completed Sligo Bridge with the previous bridge being inundated by the reservoir being formed.
