The M7 road system was constructed +30 years ago using bulldozer construction, as was common during that era. There had been road prism failures in several places along the road system. Prior to this project there was high potential for additional failures in the road prism and downslope. This project involved completing deactivation of a portion of the road system. This work was a continuation of work started in 2003 but suspended due to snowfall. The work was done to improve the road prism and downslope stability, and to return subsurface and surface runoff to pre-road conditions.
