Bochum is connected to the Autobahn network by the A 40, A 43 and A 44 autobahns. In addition, Bochum has a ring road, built to expressway standards, consisting of four segments; the Donezk, Oviedo, Nordhausen and Sheffield-Ring roads. It serves as a three-quarter loop around central Bochum and begins and ends at Autobahn A40. Ruhr University Bochum is also served by an expressway running from the Nordhausen-Ring to Autobahn A43. Until 2012, a new interchange (Dreieck Bochum-West) between the Donezk-Ring and Autobahn A40 is being constructed within tight parameters due to the existence of a nearby factory.
Apart from the autobahns and expressways, there is also a small ring road around the center of Bochum, where most roads radiating out of Bochum begin. Most main roads in Bochum are multi-lane roads with traffic lights. Bochum is also served by the Bundesstra�e 51 and Bundesstra�e 226. B51 runs to Herne and Hattingen, and B226 runs to Gelsenkirchen and Witten.
Bochum has a central station situated on the line from Duisburg to Dortmund, connecting the city to the long-distance network of Deutsche Bahn as well as to the S-Bahn network of Rhine-Ruhr.
Local service is supplied by BOGESTRA, a joint venture handling transportation between the cities of Bochum and Gelsenkirchen. There is a single underground Stadtbahn line connecting the University of Bochum to Herne, and several lines, partially underground, connecting to Gelsenkirchen and Witten. Public transport in the city is priced according to the fare system of the VRR transport association.
Bochum is served by D�sseldorf International Airport
