This bridge is still open to railroad traffic. Some of the cut stone looks like it was left over from an original (most likely wooden) bridge that the Kansas City, Springfield, and Memphis Railroad (later Kansas City, Fort Scott, and Memphis-aka the Gulf Railroad) built back in the 1880's. This bridge was most likely built by the Frisco (St. Louis and San Francisco) Railroad in about the 1910's. Frisco was bought in the 1960's by Burlington Northern which merged in about 2000 with Santa Fe which is not the Burlington Northern/Santa Fe. This particular line goes down through norther Arkansas all the way to Memphis.
