Many U.S. bridges were built during the 1960s. Evaluating the structural condition of these bridges under today's traffic loads and safety expectations is difficult. This project is developing a practical program for structural health monitoring of Alaska's bridges. Researchers are conducting a literature review to summarize the current knowledge available in SHM technology, surveying ADOT&PF staff to determine which technologies are currently in use, and making recommendations on what techniques should be pursued to implement a successful SHM suitable for cold regions.
