Bridges are under various loads and environmental impacts that cause them to lose their structural integrity. A significant number\r\nof bridges in US are either structurally deficient or functionally obsolete, requiring immediate attention. Nondestructive load\r\ntesting is an effective approach to measure the structural response of a bridge under various loading conditions and to determine\r\nits structural integrity. This paper presents a load-test study that evaluated the response of a prefabricated bridge with full-depth\r\nprecast deck panels inMichigan. This load-test programintegrates optical surveying systems, a sensor network embedded in bridge\r\ndecks, and surface deflection analysis. Its major contribution lies in the exploration of an embedded sensor network that was\r\ninstalled initially for long-term bridge monitoring in bridge load testing. Among a number of lessons learned, it is concluded that\r\nembedded sensor network has a great potential of providing an efficient and accurate approach for obtaining real-time equivalent\r\nstatic stresses under varying loading scenarios.
