[edit] Construction

At the time of the Memphis bridge construction, it was a significant technological challenge and is considered to be chief engineer George S. Morison's crowning achievement. No other bridges had ever been attempted on the Lower Mississippi River. Besides the difficulty of crossing this far south, Morison was required to provide at least 75 feet clearance, have a main span of more than 770 ft for the main river channel. He was also required to provide for vehicular and pedestrian traffic on the same level as the rail traffic. Construction for the Kansas City, Fort Scott and Memphis Railroad began in 1888 and was completed May 12, 1892. In the end the project created a bridge that was the farthest south on the Mississippi River, featured the longest span in the United States and cost nearly 3 million dollars.[1] A testament to its design and construction, as of 2006 the bridge is still used by BNSF Railway. The bridge is listed as a Historic Civil Engineering Landmark. [2]
