I-76 Over Clear Creek Scour Mitigation

About the Project:

This is a state-funded bridge scour mitigation project in Adams County. Work includes 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 is frequently referred to as bridge scour which can over time lead to bridge failure. To manage the risk of bridge failure, counter measures are used to mitigate scour effects.

Project Benefits:

  • Crews are reinforcing the pier walls and placing boulders to mitigate erosion under I-76
  • Scour mitigation is critical to maintaining structural integrity to bridge piers

Work Schedule:

The project began on Friday, Nov. 4, and will last until early spring 2023.

  • Working hours are 7 a.m. to 6 p.m. Monday to Friday
  • Some Saturday work is expected.

Traffic Impacts:

  • No traffic impacts are expected on I-76
  • Construction crews and equipment will be intermittently crossing the Clear Creek Trail at the work zone.
  • Flaggers will be in place to manage pedestrian and cyclist traffic during these intermittent path obstructions on the Trail.
