81. The techniques used during the temporary or permanent closure of a road must prevent the obstruction of the water flow and the sedimentation in watercourses. They must also ensure the free flow of fish to the crossing site in situations other than those described in section 103.
Where a road, closed permanently, has bridges, culverts or removable structures, they must be removed when the road is closed. After their removal, the bed and banks of the watercourses must be stabilized. The vegetal cover in the strip of woodland or the strip of land referred to in section 27 or 34 must be reconstituted. The right-of-way of the road must be reforested over a minimum length of 250 m from the point of closure or up to the first bridge, culvert or removable structure removed in order to make use impossible. Reforestation must be carried out within 2 years using species adapted to the site.
The renewal of the vegetation cover and reforestation of the right-of-way of the road, provided for in the second paragraph, do not apply to forest development activities carried out in the right-of-way of power transmission lines by the holder of a forestry permit issued for public utility works.
