A strategic road designed to supply the various bunkers in the section from Crusnes to Morfontaine. Walk past the Serrouville airport, which is used by hobby pilots. There is more traffic on the airfield than the condition of the road suggests. The street has a very stable substructure, but the ceiling has lost its tar for a long time and is more like a slope. Huge puddles, especially after rains, but all have firm ground. Go straight past the bunkers in Bréhain. Very long way through the forest that only crosses a road once. In places meanwhile gravelly, but can be used by all bicycles. Except racing bikes. Crosses the former railway line from Aumetz to Audun, the rails are still lying. If you find them, however, you are GOOD.
