Bruchsal Rollenberg junction is a complex flying junction at the intersection of Mannheim–Stuttgart high-speed railway with the Heidelberg–Karlsruhe line and is located between Bruchsal and Ubstadt in the German state of Baden-Württemberg.

The Ubstadt connecting curve (German: Verbindungskurve Ubstadt) branches off the line from Heidelberg in the northwest at Ubstadt-Weiher junction. The Bruchsal connecting curve (Verbindungskurve Bruchsal) branches off the line from Bruchsal and Karlsruhe in the southwest at Bruchsal Nord junction.

Bruchsal Rollenberg junction (Deutsche Bahn abbreviation: RROL) is located at the north west portal of Rollenberg Tunnel and thus where the Upper Rhine Plain meets the Kraichgau hills. The two-track high-speed line is connected to the three tracks of the Mannheim–Heidelberg–Karlsruhe line by the two tracks of the Ubstadt connecting curve from Mannheim and Heidelberg in the north and by the single-track of Bruchsal connecting curve from Karlsruhe in the south.

The two curves span an area of 50 hectares. In this area, there are parts of the now disused and sealed Bruchsal district landfill and the junction of the Bruchsal–Odenheim line with the Karlsruhe–Heidelberg line and the landfill siding.

The two tracks of the Ubstadt connecting curve separate at the grade-separated Ubstadt-Weiher junction (abbreviation: RUWA) from the Heidelberg–Karlsruhe line and run to the southeast. Trains on the southern track from Heidelberg run above the high-speed line before connecting with the track of the high-speed line that is used by trains running to the southeast. The northern track, which is designed for operations at 150 km/h, is used for trains running to Heidelberg. Both tracks connect with the track of a high-speed line that is appropriate to their direction of operation at the grade-separated Rollenberg junction.
