Rehabilitation of the Devon Bridge Over Housatonic River M&J Engineering Project Location: Stratford and Milford, Connecticut Project Start Date: 1 July 2021 Project Completion: 15 December 2023 Project Team: Connecticut Department of Transportation (CTDOT) Domenic Larosa, M&J Engineering Stacey Epps, Close Jensen, and Miller, P.C. (CJM) John Miller, Mohawk Northeast, Inc. Project Background: The Rehabilitation of the historic Devon Bridge stands as a testament to M&J Engineering’s commitment to preserving vital infrastructure with innovative solutions. This bascule draw bridge, stretching 859 feet across the Housatonic River and linking Stratford and Milford, is the longest drawbridge on the Boston Post Road and has been listed on the National Register of Historic Places since 2004. To restore this vital structure to a “State of Good Repair,” M&J, working with Mohawk Northeast, Inc., Close, Jensen & Miller, P.C., and the Connecticut Department of Transportation (CTDOT), undertook extensive efforts to address the structural deterioration and wear affecting its steel and concrete elements. As part of the scope of work, the rehabilitation addressed balance issues related to the bridge’s movable span. In preserving this historic drawbridge, M&J Engineering’s team honored its storied past while preparing it for continued service, showcasing a blend of technical expertise and respect for Connecticut’s engineering heritage. Impact: As a historic structure and vital connector between Stratford and Milford, the bridge supports a substantial flow of both commercial and residential traffic, easing pressure on nearby routes such as I-95. The project enhanced safety and reliability for thousands of daily users, ensuring that residents and local businesses continue to enjoy efficient access across the Housatonic River. Environmentally, the use of Ultra High- Performance Concrete (UHPC) was a strategic choice for its durability and extended lifespan—up to 50 years, compared to the typical 20 years for standard concrete. This longevity minimizes the need for future repairs, thereby reducing the consumption of materials and energy required for maintenance. Throughout the project, meticulous planning ensured that construction activities minimally disrupted the local community. Keeping the bridge operational allowed uninterrupted flow of vehicular and marine traffic, supporting the daily routines of residents and preserving access to the Long Island Sound.
