Tennessee Trail Bridge: A Landmark of Innovation & Natural Integration
The Tennessee Trail Bridge, crafted by York Bridge Concepts (YBC) for the Tennessee Valley Authority (TVA), stands as a shining example of sustainable engineering and natural harmony. This 300-foot timber pedestrian bridge not only enhances access along TVA's public trailway system in Harriman, Tennessee, but also gracefully crosses a tranquil lake, complete with a navigable pass-through for boaters.

Designing a 300-Foot Tennessee Trail Bridge Over A Lake
YBC's Tennessee Trail Bridge consists of multiple spans--one 20-foot span and twenty-eight 10-foot spans--together forming a continuous 300-foot structure. Elevated 20 feet above grade, it offers breathtaking views of the lake and surrounding landscape. Its construction accommodates pedestrians, horses, above and watercraft vehicles below, ensuring seamless experiences for walkers and boaters alike.
Sustainable Materials & Innovative Construction
The bridge's design incorporates CA-C treated Southern Yellow Pine, a material chosen for its natural durability and resistance to decay. YBC's skilled builders utilized timber piles and abutments for the foundation, finished with acrylic/polymer coatings to enhance longevity. The 1.5-inch decking provides a sturdy and comfortable walking surface, while the Decero™ Wire Mesh Design Series handrails offer safety without obstructing the stunning lake views.
Minimizing Environmental Impact with Deck-Level Construction
The Tennessee Trail Bridge showcases YBC's commitment to environmental stewardship. Using a deck-level construction approach, the project minimized disruption to the natural terrain and preserved the delicate lake ecosystem. The multi-span design allowed enough space for vessels to pass underneath while minimizing the amount of pilings to be driven into the lake bottom.
A Legacy of Thoughtful Design and Community Engagement
The collaboration between TVA and York Bridge Concepts has resulted in a Tennessee Trail Bridge that embodies thoughtful design, environmental responsibility, and a lasting impact on the local community. This bridge not only connects trails but also connects people to nature and to each other.
