Green Springs Road Cantilever Through Truss Bridge

1 3-span continuous Warren (PTC) cantilevered through truss bridge. One of 3 cantilevered through truss bridges built by TVA after it impounded dams on rivers in East Tennessee. This one is on the Holston River, South Fork, and the embayment is South Holston Lake. View is southbound, north of VA-TN border. Others are in Jefferson County and Grainger County, both Tennessee.

The old truss is now completely gone.

In comparing "before" and "after" topographic maps which are now available on the USGS web site, it appears that the Avens bridge was relocated when South Holston Dam was constructed. The original location was in the Abingdon quadrangle, upstream of the current site.

At this time, it was not uncommon for bridge components, such as truss sections, to be salvaged from TVA project areas and re-cycled for use at new locations. I do not know of any specific instances in the so-called "TVA Upper Holston Projects."
