9. A holder of a management permit who lays out a trail across a watercourse or a fish habitat shall install bridging. At the end of the work, the permit holder shall remove the bridging.
The first paragraph does not apply to a person who lays out an ice bridge, provided that he stabilizes the banks with log mats that are interconnected and are installed across the full width of the trail. Upon completion of the work, he shall leave those mats in place and, if necessary, remove the log frame that was used to reinforce the ice bridge.
