Description 

The nine Melan arch viaducts on Union Avenue were an integral part of the overall tour route through Vicksburg National Military Park, providing visitors safe and easy access to points of interest, uniformity and continuity in the park landscape. Bridge No. 8, spanning the Illinois Central Railroad, was removed in the 1960s, leaving eight of the original nine bridges.
