Because of the multitude of hazards and the potential for environmental damage inherent in traditional dredging and bridging river-crossing methods, pipeline constructors have spent much effort to develop alternative techniques. The most successful of these is directionally controlled horizontal drilling, which involves digging a curved hole underneath the riverbed to contain the pipeline. This faster method buries the pipe deeper, does not disrupt marine traffic either during or after construction, and leaves the riverbed and banks completely unchanged; in addition, the drilled crossings are essentially maintenance-free.
