Bundesautobahn 3 (translates frae German as Federal Motorwey 3, short form Autobahn 3, abbreviatit as BAB 3 or A 3) is an autobahn in Germany that links the border wi the Netherlands near Wesel in the northwast tae the Austrick border near Passau in the sootheast.
Major ceeties along its tot length o 778 km (483 mi) include Oberhausen, Duisburg, Düsseldorf, Leverkusen, Cologne, Wiesbaden, Frankfurt, Würzburg, Nuremberg an Regensburg. The A 3 is a major connection atween the Rhine-Ruhr aurie an soothren Germany, resultin in hivy traffic. Consequently, lairge pairts hae three lanes (plus emergency lane) in each direction, includin a 300 km (187.5 mi) long pairt atween Oberhausen an Aschaffenburg.
The first plans for the segment atween Cologne an Düsseldorf date tae 1925, an a bypass segment 2.5 kilometres (1.6 mi) long at Opladen wis built beginnin in 1931 an opened on 27 September 1933. The remainder o the highwey atween Oberhausen an Wiesbaden via Cologne wis constructit in sections as pairt o the Reichsautobahn network, till 1940. The first o these, the 25 kilometres (16 mi) segment atween Cologne-Mülheim and Hilden, opened on 21 May 1936. The 41.5 kilometres (25.8 mi) stretch atween Limburg an Dierdorf opened on 15 Juin 1940, an that atween Erlangen an Nuremberg wis completit in 1941, although in ane direction only ower pairt o the segment. However, wirk on the stretch sooth o Wiesbaden, includin the bridge ower the Main at Eddersheim, wis suspended in 1943. The northren segment tae the border wi the Netherlands, the so-cawed "Holland Line", wis begun in 1939 an suspended in 1942; wirk resumed on this segment in 1958 an it opened in sections atween 1961 an 1965. Wirk also began in 1939 on a segment atween Regensburg an Wörth an der Donau, which wis tae hae included a bridge ower the Danube at Regensburg an a bypass north o Deggendorf, but wirk wis suspended in or before 1942, an this segment (passin sooth o Deggendorf instead o north) wis only completit in the 1960s. The pairts in Eastren Bavarie were built significantly later, wi the last gaps bein closed in 1984.
The A 3 runs parallel tae the Bundesstraße 8, which it thus replaced as a main highwey. Baith follow the medieval trade route Via Publica that wis first mentioned in a document frae 839.
