The building OH16 is situated in the campus north of the TU Dortmund, close to the motorway intersection Dortmund West, where the Sauerlandlinie A 45 (Frankfurt-Dortmund) crosses the Ruhrschnellweg B 1 / A 40. From here the university is connected to the west with the motorway network of the Ruhr Area and beyond that to the regions of the Lower Rhine and the Netherlands. In the eastern direction the B 1 leads through Dortmund to Unna, where there is a connection with the motorways leading to Bremen, Hannover/Berlin and Kassel. In the north, the A 45 ends after a few kilometres at the A 2, leading to the Kamener Kreuz and in the other direction to Oberhausen. In the Westhofener Kreuz, south of the university, the A 45 crosses the A 2, leading to Bremen and Köln. The best motorway exit on the A 45 is "Dortmund-Eichlinghofen" and on the B 1 / A 40 "Dortmund-Dorstfeld" or "Dortmund-Barop". There are signs at all exits leading you to the university.
