Vicksburg has been an important railroad town since before the Civil War. One of the reasons General Grant considered this to be a crucial strategic objective in the Civil War was the railroad infrastructure. The railroad from the western Confederate states (Texas and Louisiana) came through Vicksburg on the way to Jackson, Meridian, and other eastern Confederate cities. Once Vicksburg surrendered, the Union Navy totally controlled the Mississippi River and the Confederacy was split. This meant food and other crucial supplies could not move east from the western states.
The train still comes through Vicksburg. Let us take a quick tour of the railroad bridges in town. I suspect many motorists just rush over and do not pay any attention to the tracks below.
