Until 1824, Harper's Ferry relied on the ferry of the same name for transportation across the Potomac River. Since then, five bridges have been built over the Potomac, though only two are still standing. These bridges would be one of the factors that made Harpers Ferry into one of the most sought after positions in the Civil War, where it changed hands eight times between 1861 and 1864. The crossing was added to the National Register of Historic Places in 1978.

Until 1824, the town of Harpers Ferry and the surrounding area had to rely on a ferry of the same name for reliable transportation across the Potomac River. The first bridge was constructed in 1824 and was a wooden road. This was replaced in 1839 by a covered wooden truss about eight hundred and thirty feet long and capable of supporting the weight of a steam engine. An additional bridge was constructed alongside it in 1851, this time made out of metal in the Bollman Truss design.

These two bridges were massive targets during the Civil War. Due to Harpers Ferry's relative proximity to the capital, they made the town into an immensely valuable strategic location. Controlling the Harpers Ferry junction was an effective choke-point to the north or the south. During the three years of fighting, Harpers Ferry changed hands eight times and the wooden bridge was destroyed in 1861.

After the Civil War, two more bridges were constructed in 1894 and 1930 to accommodate the increasing weight of newer steam trains. The Bollman Truss bridge had been replaced with a new version in 1870, but it was washed away in a flood in 1936, leaving only the piers that used to hold it up. Both of the remaining bridges are now used by CSX for its Shenandoah (1894 bridge) and Cumberland (1930 bridge) Lines. The crossing was added to the National Register of Historic Places in 1978.
