The bridge was designed for a 75-year lifespan. It was built in 1961, meaning it will reach the end of its design life in 2036. However, current factors could contribute to a shortened lifespan, including that the bridge was never designed for the current volume of traffic. As a result, an increased need for repairs and/or replacement is expected.
