This narrow point on the Mississippi River near Memphis, TN features three lovely crossings: The Frisco Bridge (1892), the Harahan Bridge (1916), and the Memphis-Arkansas Bridge (1949).
The Harahan Bridge is a cantilevered through truss bridge constructed by the Arkansas & Memphis Railway Bridge & Terminal Company under the supervision of famed consulting engineer Ralph Modjeski. Its total length of 4,973 feet includes an asymmetric collection of cantilevered, suspended, semi-suspended, and deck truss spans - the longest of which is the western-most span of 791 feet. It was originally named the Rock Island Bridge, but was subsequently renamed for Memphis businessman J.T. Harahan, who was president of the firm that built the bridge and who was killed in a 1912 train wreck.

The wooden-planked roads were apparently a terrifying travel experience and they were prone to fires started by sparks from passing locomotives. The Harahan was the primary vehicular bridge in this area until the neighboring Memphis-Arkansas bridge opened in 1949. As of this writing in 2011, there are plans to recover the roadway as a recreational pedestrian trail.
In contrast to the largely rebuilt Eastern roadway approach, the remnants of the Western roadway approach are fairly readily accessible (albeit overgrown) from exit #1 down Dacus Lake Road (the local road signs call it Eddie Garey Road).
I had noticed the remnants of the abandoned roadways numerous times when passing through Memphis on I-55, but had never had the time to explore further.
In the summer of 2011 I had the time...
