• A 50-foot wide pipeline right-of-way contained one 8-inch diameter pipeline inside of a 10-inch casing. The pipeline was exposed across the entire 130-foot Mad River crossing in Montgomery County, Ohio. The pipeline was also suspended over a 5-foot deep by 30-foot long scour hole.

  • Holly Creek crosses a 30” gas transmission pipeline at nearly a 45° angle. The pipeline has a concrete cap poured on top to provide cover. The creek bed has degraded downstream of the pipeline, and the pipeline is exposed along the left bank.

  • A 30-inch diameter natural gas transmission pipeline crosses at the confluence of the White River and the East Fork of the White River. The White River had laterally migrated and the right, descending, high bank eroded to expose the pipeline.
