Map with all coordinates: The Bundesautobahn 672 (abbreviation: BAB 672 ) - short form: Autobahn 672 (abbreviation: A 672 ) - is a motorway in the German state of Hesse . It mainly serves as a connection between Darmstadt city center and the federal highways 67 and 5 . With a length of only around 2.5 km, it is the second shortest motorway in Germany after the 2.3 km long BAB 831 .
course
Northwest of Griesheim , the A 672 branches off from the A 67, heads east and crosses the A 5. Then, east of the Tann settlement , the motorway meets the B 26 , also coming from Griesheim , with a junction in the form of an elongated right-hand trumpet is connected. The continuation of the autobahn is the B 26, which runs as Rheinstrasse into Darmstadt's city center and behind the city, expanded like a freeway, to Aschaffenburg .
Coming from the A 5 you can only change to the A 672 in the direction of Darmstadt, the junction only has connections to and from the east. If you want to change from the A 5 from Frankfurt am Main to the A 67 in the direction of Rüsselsheim am Main , you either have to use the A 3 from the Frankfurter Kreuz or the B 42 from the Weiterstadt junction to the Büttelborn junction of the A 67 A corresponding connection is not required in the south, as the A 5 and A 67 to Mannheim run parallel to each other and are connected by several roads. Corresponding ramps are also missing in the Darmstädter Kreuz immediately to the south.
Coming from the south, you are advised to leave the main carriageway of the A 5 or A 67 at the Darmstädter Kreuz to get onto the A 672. In theory, it would also be possible to keep the main lane and still switch to the A 672, but then you would have to change lanes several times in the area of the acceleration lane. When changing the main lane you will automatically get to the turning lane of the A 672.

history
Reichsautobahn junction Darmstadt
The city of Darmstadt has had a connection to the motorway network since May 1935, when the Frankfurt – Mannheim – Heidelberg line was the first Reichsautobahn from the Nazi era . Although were Cologne and Bonn in 1932 connected to each other via the first German motorway, this was after the seizure of power downgraded Hitler, however, the road to the construction of the "first highway" to reclaim for themselves.
The junction formed the border between the Frankfurt – Darmstadt section completed in May 1935 and the continuation to the south via Mannheim to Heidelberg, completed in October. It led east of Griesheim , at the level of the Tann settlement, on long-distance road 26 (today's Bundesstraße 26 ), which at that time still began in Mainz and led south-east towards Darmstadt. On the eastern side of the road there was a petrol station in the area of the junction, the first autobahn petrol station in Germany.
Main-Neckar expressway with connection to Rheinstraße
After the end of the Second World War, private transport increased sharply with the economic miracle , especially in the metropolitan areas. At the end of the 1950s, the Darmstadt – Mannheim route was the busiest motorway in Germany with around 40,000 vehicles per day. In the early 1960s, construction work began on a second north-south stretch between the two metropolitan areas. Due to the route from the Cologne – Frankfurt route to the southeast and from Darmstadt parallel to the east of the existing motorway, it represented an alternative while avoiding the Frankfurt junction, which was already heavily used at the time . Building was gradually carried out from north to south, until 1970 with the last section between Weinheim and Heidelberg the Main-Neckar expressway was completed.
By 1965, the new line, which was largely built on the route of the existing B 26, came to an end shortly before Griesheim when coming from the northwest. The section from Griesheim to Darmstadt-Eberstadt (at that time the Pfungstadt junction ) was built from 1964 and released in two sections in 1966 and 1968. At the intersection with the existing Frankfurt – Mannheim motorway, a motorway junction was created where both motorways intersect at an acute angle. Since the routes run largely parallel to one another, only connecting ramps were built here from north to south and vice versa. The previous junction on the B 26 would not have been directly accessible from the north-west.
In order to connect the B 26, which was relocated in the course of the new autobahn construction and is now starting west of Griesheim bei Riedstadt - Wolfskehlen , to both highways, an approximately 2.5 km long feeder (BAB branch Darmstadt) was built north of the Darmstädter Kreuz Darmstadt city center can be reached from both routes. It is not possible to use this to switch between the two autobahns, as all connecting ramps lead out and towards Darmstadt. It is unclear exactly when the feeder was opened: The bridge structure over the old Frankfurt – Darmstadt line was opened to traffic on July 30, 1965, the feeder was opened to traffic at the beginning of 1970, after construction work began in February 1966. The previously existing junction with the B 26 was closed when the feeder went into operation.
Introduction of the numbering system
When the new numbering system for federal motorways was introduced on January 1, 1975, it was given the name Bundesautobahn 672 , or BAB 672 for short . The name is derived from the BAB 67 (northern section of the Main-Neckar Schnellweg since 1974 ), from which it branches off. At the Darmstädter Kreuz to the south, the federal highways 5 and 67 have since changed numbers in order to avoid double numbering that would otherwise follow near Mannheim.
expansion
New bridge construction
From October 2012 to November 2014, the bridge structure over the A 5 in the Darmstadt triangle (A 5 / A 672) was rebuilt for 13.5 million euros . At the same time as the new bridge, the lanes were also re-marked, so the main carriageway now narrows to one lane west of the junction, the second lane continues from the Frankfurt – Darmstadt ramp. This eliminates the need for threading this busy connection.
The entire signage was also renewed in the course of the renovation - instead of the federal highway 26, the number of the motorway (A 672) is now indicated in the east direction. Previously, the number was only written on the notice boards for the A 5 and A 67, while only the A 5 and A 67 are signposted for the west and the motorway signs in Darmstadt.
Designation of the nodes
Until the beginning of 2016 and 2018, the junctions of the A 672 with the A 5 and the A 67 together with the Darmstädter Kreuz to the south, with which they share a junction number on each of the two motorways, were not shown separately. Although the names Dreieck Darmstadt / Griesheim and Dreieck Darmstadt were given for administrative purposes and in most road maps and atlases , they were not included in the route. On older map material, the junctions were named Darmstadt / Griesheim and Darmstadt West , the transition to the B 26 Rheinstrasse .
Since 2016 the junction A 5 / A 672 has been called Darmstädter Nordkreuz . Since 2018 the junction A 67 / A 672 has been signposted as the Griesheimer Dreieck .
