Bundesautobahn 98
is a long motorway in southern Germany, originally intended to connect Weil am Rhein with the A 8 near Irschenberg.
Currently, only three relatively short unconnected sections have been constructed:
- Weil am Rhein to near Eichsel, where the road diverges south to become the A 861 towards Rheinfelden (Baden) and the Swiss border;
- east of Waldshut-Tiengen to north of Lauchringen; and
- north of Singen to north of Überlingen.
