A 1.2km stretch of road was expanded to create the new north bypass road, which joins the L1156 500m east of Mutlangen at a newly-built roundabout. This building project meant that 300m of the L1156 had to be rebuilt to join the local through road.

A slip road joins the newly-built west bypass road B298, which was constructed as an at-grade intersection with traffic lights according to the basic form 1. 100m east of this slip road, another at-grade intersection was built according to the basic form 1 to join Mutlangen to the west and to provide access to a service station and a car dealership.

One particularly challenging task was to integrate the planned 34m ø roundabout harmoniously into the extremely hilly surrounding terrain. Yet despite the considerable topographic height differences it was completed extremely successfully. And as improved road-user safety was demanded, the intersection was designed as a roundabout. Indeed the use of traffic islands in the approach roads as an aid to crossing much improved the safety of pedestrians, cyclists and, especially, school children from the suburb Schwäbisch Gmünd-Lindach.
