Road traffic in the Rhine-Neckar triangle

The first automobile drove on Mannheim's streets in 1886 . Even today, the greater Rhine-Neckar triangle around the large cities of Mannheim, Ludwigshafen am Rhein and Heidelberg is well connected to the long-distance transport network.

Motorway network

Main roads (at least four lanes) in and around the Rhine-Neckar triangle

The A 5 ( Frankfurt - Heidelberg - Karlsruhe - Basel ) and A 6 ( Saarbrücken - Mannheim - Heilbronn - Nuremberg ) motorways intersect south of Heidelberg at the Walldorf junction . Together with the A 61 on the left bank of the Rhine ( Cologne - Koblenz - Ludwigshafen), which joins the Hockenheim triangle , they create national connections in all directions.

The A 67 increases the capacity from Mannheim towards the Rhine-Main area , the A 65 connects Ludwigshafen with the southern Palatinate and Alsace .

The A 650 , A 656 and A 659 motorways as well as the B 9 from Worms to Wörth (near Karlsruhe) complement the network .

The A 6 and A 61 motorways completely surround Mannheim and Ludwigshafen and thus form an outer motorway ring.

A dense network of federal highways creates connections within the metropolitan area and into the neighborhood.

The Federal Highway 3 ( Hamburg - Frankfurt - Basel ) is one of the oldest and longest federal roads in Germany. From Frankfurt it runs parallel to the A 5 via Darmstadt along the Bergstrasse to Heidelberg and from there to Karlsruhe.
The B9 extends linksrheinisch from the Dutch border on Köln and Mainz to the French border at Karlsruhe. From Worms to Wörth, it is continuously expanded to four lanes.
The B 271 runs north-south in the west, the B 36 to the south and the B 44 to the north . There is also the North Baden B 291 .

The federal highways 38 (in the north), 47 and 39 (in the south) as well as the 37 diagonally run in west-east direction .
There is also the four-lane expressway B 535 between Heidelberg and Schwetzingen and the south Hessian B 460 .
