Both of the emergency access roads are marked access=official, which suggests the Garmin routing is not respecting this access restriction tag.
Checked the OSM Wiki and it turns out that access=official is not the proper tag to use; rather access=no should be used. Also added psv=yes to allow public service vehicle access.
