The Vermont Agency of Transportation's ambitious $28.3 million project to replace the Readsboro Bridge on VT Route 100 is progressing despite significant engineering challenges. With completion expected in the winter of 2027–2028, this critical infrastructure project promises to enhance local connectivity and safety.
What Happened
The Readsboro Bridge, originally built in 1954, is undergoing a full replacement due to its structurally deficient condition. Harrison & Burrowes Bridge Constructors have been at work since February 2025, constructing a new 374.5-foot, two-span bridge designed to meet current AASHTO standards. The existing Bridge 25, a 340-foot-long structure, was deemed inadequate due to its poor deck and superstructure condition, leading to the decision for a complete overhaul. The new bridge will feature two 11-foot travel lanes, 3-foot shoulders, and a sidewalk, supported by concrete abutments and a pier on drilled shafts.
The project faced diverse geotechnical conditions, requiring innovative engineering solutions such as the use of fiber-reinforced polymer bridge drains and weathering steel plate girders. A temporary three-span ACROW bridge is currently maintaining traffic flow during construction. The project, designed by VHB, entered the delivery program in 2013 and has been carefully planned to mitigate disruptions, with the contractor allowed up to four weekend closures for major construction activities.
What This Means for Your Business
For AECM professionals and government contractors, the Readsboro Bridge project highlights the importance of adaptive engineering solutions in the face of complex site conditions. This project underscores the critical need for robust project planning and risk management, particularly when dealing with infrastructure deemed structurally deficient. The use of modern materials and design standards not only extends the service life of such projects but also improves safety and reliability, offering a model for similar infrastructure undertakings.
This project also presents opportunities for contractors specializing in bridge construction, as well as suppliers of advanced construction materials. The integration of cutting-edge technologies and materials in such projects can lead to competitive advantages and potential federal funding opportunities.
What US Operators Should Watch
AECM professionals should monitor the progress of the Readsboro Bridge project as a benchmark for future infrastructure projects. Key deadlines include the winter 2027–2028 completion target, with critical construction phases occurring through the 2026 season. Additionally, contractors should pay attention to procurement opportunities and potential federal funding for infrastructure projects that require innovative engineering solutions and materials.
Operators should also keep an eye on compliance requirements with current AASHTO standards and ensure readiness for similar projects that may arise as states address aging infrastructure. The project serves as a reminder of the importance of maintaining compliance with evolving engineering standards and leveraging advanced materials to extend the lifespan and safety of critical infrastructure.
