Black River Bridge at Pocahontas, Arkansas on March 12, 1981 (R.R. Taylor).
The Hoxie Sub crossed the Black River over Bridge 245.1. The ETT referred to the bridge as a “drawbridge”, and local history has it that the bridge over the Black River at Pocahontas was the largest turn-span west of the Mississippi….That is at least at the time of its construction.
From south to north the bridge consisted of a:
542 foot long open-deck pile trestle, the piles were last renewed during 1929,
54 foot deck plate girder,
440 foot riveted truss (turn)
80 foot deck plate girder,
65 foot deck plate girder.
1181 feet total length.
Thanks to Karl Brand for the details.
