NHDOT Leads Elegant Bridge Solution to Historic Challenges, Hinsdale, New Hampshire

The General John Stark Memorial Bridge project, led by the New Hampshire Department of Transportation (NHDOT), replaced two aging and functionally obsolete crossings over the Connecticut River with a single, modern structure. At approximately 1,800 feet, this bridge is the third longest in New Hampshire and the first new crossing over the river in two decades. The project significantly improves safety, reduces maintenance costs, and enhances regional connectivity for vehicles, pedestrians, and cyclists. By diverting traffic from downtown Brattleboro, it improves the quality of life for Hinsdale residents and strengthens economic ties between New Hampshire and Vermont through improved freight, commerce, and tourism links.

The design and construction incorporated advanced engineering techniques, including a horizontally curved alignment, parabolically haunched girders, and large-diameter concrete-filled steel pipe piles to optimize structural efficiency and minimize material consumption. McFarland Johnson (MJ) partnered with NHDOT to provide critical environmental permitting services and developed an independent finite element bridge model to ensure safety and performance throughout construction. Extensive public outreach, including 3D visualization integrated into Google Earth, fostered strong stakeholder support. This landmark project not only fulfills NHDOT’s mission to connect communities safely and efficiently but also serves as a model for sustainable and innovative design, as well as effective public engagement for future infrastructure projects.
