Michigan Ditch Tunnel Project

  • Michigan Ditch

Trans-mountain water is not running this year in the Michigan Ditch due to an ongoing landslide that covered part of the ditch in 2015. Many options were considered to repair the damage to the ditch and a tunnel was determined to be the best solution.

Weather permitting, construction will begin as soon as the snow can be cleared in May and the tunnel will be completed by late fall. The ditch road will be closed to all public access for the summer of 2016.
