Road transport

Stuttgart is served by Autobahn A8, that runs east–west from Karlsruhe to Munich, and Autobahn A81 that runs north–south from Würzburg to Singen. The Autobahn A831 is a short spur entering the southern side of Stuttgart.

Besides these Autobahns, Stuttgart is served by a large number of expressways, many of which are built to Autobahn standards, and were once intended to carry an A-number. Important expressways like B10, B14, B27 and B29 connect Stuttgart with its suburbs. Due to the hilly surroundings, there are many road tunnels in and around Stuttgart. There are also a number of road tunnels under intersections in the center of Stuttgart.
