  • Abstract:
    This project included the “Living Bridge” group efforts to create a benchmark example of a self-diagnosing, self-reporting, “smart infrastructure” at the Memorial Bridge (Portsmouth, NH, and Kittery, ME) to further advance a National Science Foundation (NSF) funded project, the “Living Bridge Project (LBP)”, seeking to promote infrastructure sustainability on three fronts by: (1) installing a small structural, environmental sensing network that is powered by clean energy innovation in tidal energy conversion, while (2) assessing how the tidal turbine installed at the bridge pier impacts the bridge structure and environment; and (3) deploying an innovative, interactive community engagement strategy. The structural design of the Memorial Bridge included several innovations (e.g., gusset-less truss connections) that were monitored and evaluated long-term through instrumentation and assessed for possible use on future infrastructure projects. The proposed smart service system was mainly designed to take advantage of sensor technology and renewable energy conversion by installing a comprehensive structural, traffic and environmental sensing system to assess as accurately as possible bridge conditions in multiple key areas (e.g., traffic, structural integrity, environmental impact), and demonstrate the use of available tidal energy at estuarine bridges. The project fulfilled the Federal Highway Administration (FHWA) Technology Innovation Deployment Program/Accelerated Innovation Deployment (TIDP/AID) program goals of improving highway/bridge safety, reliability and service life, accelerating the adoption of innovative technologies, and improving highway/bridge sustainability and environmental protection. The New Hampshire Department of Transportation (NHDOT) was an eligible entity according to the AID Demonstration guidelines and Notice of Funding Availability. The proposed project was eligible for assistance under Title 23, United States Code, and initiated in 2016. The NHDOT accepted FHWA oversight of the project and worked with the FHWA to develop appropriate customer satisfaction measures.
