There is a stretch of road at Loreint that is not on the map. It runs from the east of the town to the roundabout south of the junction east of the town.

Also on the N175 there is a junction sign St Michel mount. It is not on the map but you can follow a series of roads to a rest stop by the mount.
If i find anything else like this i shall report it.
