The 1,222' (372m) long bridge has a main span of 323' (98m). Average daily traffic is 30,080. [BridgeHunter]
We are facing westbound so obviously the northern (right side in photo) bridge is the older bridge.

I could not find an elevation photo of the bridges. Both bridges have three spans.

Tennessee Memories posted Old Hickory Bridge in Nashville in 2006 Larry Law: You needed a pass to enter Old Hickory during world war ll due to the secret work they were doing at DuPont and Rayon City. That’s why the bridge has those guard houses so police could stand out of the rain and cold. |
The truss bridge replaced a suspension bridge that was built in 1918 for pedestrian traffic. That bridge had a 540' (165m) main span. Later, it was determined that it could handle cars and flagmen were stationed at each end 24-hours a day to regulate use of the one-lane bridge. [bridgemeister]
teva "While the bridge had two towers at each end, the 540-foot span had no supports to prevent sidesway and literally swayed back and forth, hence the name 'swinging bridge.'" [I had noticed a Swinging Bridge Road in the area.] |
