...you leave the A5 motorway (Karlsruhe-Basel) at the Freiburg im Breisgau exit (Freiburg -Mitte) and drive on along the motorway feeder B31a towards Freiburg.
After approx. 2.5 kilometers, you will reach Freiburg im Breisgau. After approx. 7 km, crossing the Dreisam river, turn left from the B31a to the Schwabentorring. Please keep to the right here, since you can turn right into Kartäuserstraße already after approx. 200 m. After ca. 600 m, you will have reached your destination. Kartäuserstraße 49 is located on the left-hand side immediately after the SWR Freiburg (Südwest-Rundfunk) building.
You will find parking lots in the backyard area after turning left just in front of the green building.
By train and public transport...
After having arrived at Freiburg main station, leave the platform and directly mount the stairs up to the bridge which covers and interconnects the different platforms from above and on which the line 1 tram stop in the direction of Littenweiler (Lassbergstraße) is located. Get on a tram 1 and travel up to the "Maria-Hilf-Kirche" stop. From here, you will be able to reach Atris Information Systems within 5 minutes.
To achieve this, you cross Schwarzwaldstraße to the left along your previous direction of travel. Subsequently, you walk approx. 100 m towards the city center (i.e. back again) and then turn right into Fabrikstraße. After approx. 300 m, level with a small roundabout, you will reach Kartäuserstraße, into which you turn left. Seen from this spot, the Atris Information Systems building is the very first one on the right-hand side.
