      Wow that could have been bad, but makes for a really good picture, something you don't normally see or expect to happen. I am sure the designers/engineers had never expected or anticipated this kind of thing to happen.

      There is a custom cable maker for massive equipment who had to design and manufacture the fix.
      It may of had been ~ 10 days to get the bridge working again getting barges moving passing Fort Smith.
      When they made dams on the river (1971) and the pool level rises did not allow the swing bridge to serve the needs.
      I guess it is locked now in the closed position.

      Original static spans built by the Union Bridge Company, with caisson work by William Sooysmith & Son of Chicago, the bridge was completed and the first train to cross was on February 9, 1886. The bridge was of mixed iron and steel construction. The Bridge, resting on 10 piers consisted of 4 fixed spans of 165' length on the south (Fort Smith) end, and 3 fixed spans of 256'9" on the north (Van Buren) end separated by a pivot (swing) span of 366'. The bridge was built with the provision of wood planking to permit the bridge to carry wagon traffic and for many years operated as a dual purpose railroad and toll wagon bridge.

      the bridge was reconstructed in 1913-14 with heavier trusses.
