This bridge was originally built by the Tennessee Central Railroad. It was used for passenger train access by TC trains to their passenger terminal in Harriman. Trains were turned on a "wye" track at the Emory Gap yard and then backed the last few miles across this bridge into Harriman. Southern Railroad acquired the bridge after the Tennessee Central bankruptcy in 1968. One of the photos shows a rail car on a track under the bridge. The track in that photo was owned by the Harriman and Northeastern Railroad. H&NE's passenger terminal was just to the photographers right. For several years after the beginning of the twentieth century the little town of Harriman was served by by up to five railroads simultaneously. (TC, H&NE, L&N, Southern and the CNOTP)
Here are two shots of the Emory River Bridge that were taken on my return from Spring City during the August 2017 solar eclipse. The first image is taken from the parallel N. Roane St. bridge. The second image was taken from the lumber company parking lot on the north side of the bridge.
