User MikeN restored the trails. Now you are able to go update the access tags for the trails. To do this click on the effected trails, find the "allowed access" section, and put "no" under "all". Alternatively you can go to the "Tag" section and add a new tag with "access" = "no".

Make sure to provide a source for this information, such as a link to official trail documents to show this trail is now closed and an unofficial/restricted area.

For more information about tagging trails please read about the "United States/Trails Stewardship Initiative" here:
