  • Overview

    Throughout its history, Harpers Ferry has been the backdrop for remarkable and unparalleled events. In one setting, several themes in the history of the American story converge: Native American culture, John Brown and Abolitionism, the Civil War, industry and transportation, and the natural environment. Harpers Ferry was also designated as a National Historical Park with the Appalachian Trail and the Chesapeake and Ohio Canal Towpath found within the park. And so was the challenge faced by the West Virginia Division of Highways (WVDOH) to replace an existing bridge in this storied, yet sensitive area. The WVDOH selected Modjeski and Masters, a trusted an experienced bridge firm, to develop a context-sensitive solution.

    M&M began by developing a design which took into account the bridge’s social and economic impact on the surrounding community, the National Historic Park, the Appalachian Trail, recreational users of the river, and the traveling public. Working together with the stakeholders, the results were astounding. Our technical experts implemented both innovative and existing bridge technologies, including:
    • Drilled Shafts - Designed by our bridge experts to minimize the footprint of the bridge and resulting impact on river users.
    • Reverse Curvature of the Alignment in the Horizontal Direction – An organic alignment chosen to enhance the natural beauty of the Harpers Ferry Water Gap while subtly introducing traffic calming features.
    • Uncoated Weathering Steel – A natural material choice for the superstructure to blend exceptionally well with the environment and compliments the colors of the fall foliage.
    • Span Continuity – The elimination of roadway joints to provide for a more pleasing ride for both vehicles and cyclists.
    This bridge project exceeded everyone’s expectations. It was not by happenstance, but by a well conceived, mutually agreed upon plan for collaboration among all stakeholders. This project has won several awards including the West Virginia Association of Consulting Engineers Gold Award. West Virginia, like many of our clients, trusted us to get it right the first time. And we delivered on our promise: designing great bridges that connect people and their communities.
