Instrumentation measured vibrations, deflections, stresses, movements, and rotations. Data showed increasing damage over time, including reduced frequencies, higher stresses, permanent deflections, and tendon corrosion. While monitoring identified deterioration, it allowed a 5-year delay of the planned bridge replace
