Abstract: Recently, Buchanan County, Iowa, has cooperated with the U.S. Federal Highway Administration (FHWA), USDA Forest Service, Forest Products Laboratory (FPL), and Iowa State University’s Bridge Engineering Center (ISU–BEC) to initiate a project involving the construction and monitoring of a glued-laminated (glulam) timber superstructure on geosynthetic reinforced soil (GRS) integrated bridge system (IBS) abutments. The research team from FPL installed sensors in the substructure as well as in the bearings of the girders. In addition, the research team from ISU– BEC installed sensors on the superstructure that create an autonomous structural health monitoring system for the bridge. Data are collected remotely and transmitted continuously around the clock every day. Long-term monitoring enables researchers to evaluate GRS–IBS system performance with respect to variables of time, ambient conditions, and loading.
