I-76 Over Clear Creek Scour Mitigation

Project Complete!

This was a state-funded bridge scour mitigation project in Adams County. Work included removing scour from the piers of twin bridge structures on Interstate 76 over Clear Creek and deflecting river water to the center of the channel under the bridges. Erosion of the soil around a bridge foundation,  frequently referred to as bridge scour, which can over time lead to bridge failure. To manage the risk of bridge failure, counter measures were used to mitigate scour effects.
