The Shippingport Bridge spans the Ohio River in Beaver County, Pennsylvania. Constructed in 1961, the main river crossing is a three-span, combined deck/through-truss bridge more than 1,300 feet long. As part of a larger evaluation and rehabilitation project, Lehigh University’s Advanced Technology for Large Structural Systems (ATLSS) Research Center performed field-testing of this bridge. The scope of the work included controlled-load testing using a test truck of known geometry and weight, and long-term monitoring of the bridge during normal traffic. The ATLSS then used the collected data to estimate the remaining fatigue life at critical points on the bridge. Read More
