The main autobahns are the A-5 (Frankfurt–Karlsruhe–Basel), which runs through the Rhine Valley along the western length of the Black Forest; A-81 (Stuttgart–Bodensee) in the east; and A-8 (Karlsruhe–Stuttgart) in the north. Good two-lane highways crisscross the entire region. B-3 runs parallel to A-5 and follows the Baden Wine Road. Traffic jams on weekends and holidays are not uncommon. Taking the side roads might not save time, but they are a lot prettier. The Schwarzwald-Hochstrasse is one of the area's most scenic routes, running from Freudenstadt to Baden-Baden. The region's tourist office has mapped out thematic driving routes: the Valley Road, the Spa Road, the Baden Wine Road, the Asparagus Road, and the Clock Road. Most points along these routes can also be reached by train or bus.
Freiburg, the region's major city, is 275 km (170 miles) south of Frankfurt and 410 km (254 miles) west of Munich.
