There are two railway stations, on on the Swiss side, and one on the German side.
On the Swiss side the A3 motorway runs just south of town. There are two exits, Rheinfelden and Rheinfelden Ost. A861 connects to A3 and crosses the border (and the Rhine) just west of town. It connects to the German A5 via A98.
The bridge in the middle of town serves as a border crossing for pedestrians.
The highlight of Rheinfelden is definitely the old town centre with the medieval city walls and the Roman era river fortifications.
