BW 5-2: Overpass of the Michelau connection over the Deutsche Bahn railway line and the new B 173 with a prestressed concrete bridge as a continuous girder with three spans with a total length of 154 m.

BW 5-3: Retaining wall between the new B 173 and the route of the Deutsche Bahn with a length of 154 m and a maximum height of 9.20 m.

BW 5-4: A frame structure for underpassing the watercourse with a span of 6.50 m over a total length of 41 m.
