If you are traveling to Bremen by car, you most probably are coming along the motorways A 1 (from the Ruhrgebiet or from Hamburg) or A 27 (from Hannover). On the A 1, change at the Bremer Kreuz to motorway A 27 in direction Bremerhaven/Cuxhaven. From the Bremer Kreuz, drive for about 10 kilometers (6 miles) until the exit Universität/Horn-Lehe. Take the exit to the Universität, and continue approximately 300m (1000 feet) along the Autobahnzubringer Horn-Lehe, until you reach a big crossroad at the first traffic light. Turn right into the Hochschulring. After 800m (2500 feet), after the first traffic light, you can enter the parking lot directly in front of the 'Cognium'-building.
