BAB intro|3 is an
autobahnin Germanythat links the border to the Netherlandsnear Weselin the northwest to the Austrian border near Passauin the southeast.
Major cities along its total length of 778km (483 mi) include
Oberhausen, Duisburg, Düsseldorf, Leverkusen, Cologne, Wiesbaden, Frankfurt, Würzburg, Nurembergand Regensburg. The A 3 is a major connection between Rhine-Ruhrarea and southern Germany, resulting in heavy traffic. Consequently, large parts have three lanes (plus emergency lane) for each direction, including a 300km (187.5 mi) long part between Oberhausen and Aschaffenburg. Some parts in the Cologne and Frankfurt area have been upgraded to four lanes, which is a second for German Autobahns after Darmstadt - Frankfurt (part of the A5) in the seventies.
Between Cologne and Frankfurt an ICE high-speed railway line (300km/h) closely follows the A 3's route.
The A 3 was part of the original Autobahn plans from the 1920s. Construction began between Oberhausen and Wiesbaden in 1936 and was completed in 1940. The border to the Netherlands was reached in 1942 ("Holland line"), Würzburg in the 1950s. The parts in
Bavariawere built significantly later, with the last gaps being closed in 1984. The A 3 runs parallel to the Bundesstrasse 8, which it thus replaced as a main highway. Both follow the medieval trade route "Via Publica" that was first mentioned in a document from 839.
