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.
