The report describes the instrumentation program of Red River Bridge at Boyce, Louisiana. The objectives of the program were to measure and evaluate time-dependent deformations, deflections, and temperatures of the Red River Bridge superstructure. To achieve the objectives, field instrumentation was installed on the bridge structure before and during construction. Strain and temperature sensors were placed in three selected bridge segments of one bridge span. Measurements were made for a period to five years. Concrete physical properties of the instrumented bridge segments were also measured. Using the actual material design mix, time-dependent analyses of the Red River Bridge during construction were performed. Design construction schedule was used in calculating bridge behavior during construction.
