The Remains of the Railroad Bridge
These stone piers standing in the Potomac are remnants of the long transportation history that made Harpers Ferry such an important crossroads. The narrow opening through the Blue Ridge created by the Potomac provided a natural route through the mountains, and in the nineteenth century the Baltimore & Ohio Railroad used that route as it pushed westward.

The B&O reached Harpers Ferry in the 1830s, but getting the railroad across the Potomac was a considerable engineering challenge. Over the decades, a succession of bridges crossed the river here. Floods, changing railroad technology and especially the destruction of the Civil War meant that bridges were repeatedly damaged, destroyed, rebuilt and replaced.
The surviving masonry piers in these photographs are reminders of those earlier crossings. Looking at them today, with the river flowing quietly around them, it is difficult to picture how busy this corridor once was. Trains crossed the Potomac carrying passengers, manufactured goods, raw materials and military supplies, while the nearby C&O Canal carried boats along the Maryland side of the river.
During the Civil War, control of these transportation routes was enormously important. Harpers Ferry changed hands repeatedly, and its bridges became both strategic assets and targets. Railroad bridges were destroyed and reconstructed several times as armies attempted either to maintain their own transportation connections or deny them to the enemy.
The modern railroad still passes through the same narrow river corridor, visible beside the older masonry in the second photograph. That juxtaposition is what makes these remains especially interesting. The abandoned piers are not isolated ruins. They stand beside an active railroad, allowing us to see different generations of transportation infrastructure in the same landscape.
These photographs also reinforce something that becomes clearer the longer we explore Harpers Ferry. Geography determined much of the town’s history. The rivers, mountains and narrow passages brought the ferry, canal and railroad here, and those transportation connections helped bring industry, commerce and military importance with them.
The old stone piers remaining in the Potomac are quiet evidence of that story. Even after the bridges they once supported disappeared, their foundations remain—marking the routes people have used to cross this river for nearly two centuries.

The Harpers Ferry Armory in the Civil War
This sign stands near the remains of the United States Armory at Harpers Ferry and tells the story of what happened here when the Civil War began. The location of the armory had helped make Harpers Ferry an important industrial town, but the thousands of weapons stored here also made it a valuable military target. […]
John Brown’s Family Bible
Among the objects preserved at Harpers Ferry, John Brown’s family Bible provides a particularly personal connection to the man whose actions here became part of the national struggle over slavery. Unlike a weapon, military artifact or political document, this was an object connected to Brown’s family life and to the religious beliefs that profoundly influenced […]
The Armory Fence
At first glance, these iron bars might not seem as significant as a weapon, a building or one of the personal objects associated with John Brown. But they are another surviving physical connection to the night of October 16, 1859.This is a section of the original wrought-iron fence that surrounded the United States Armory at […]
