The Federal Highway 643 (abbreviated BAB 643 ) - Short form: Highway 643 (abbreviated as A 643 ) - has a length of eight kilometers and extends from Wiesbaden on the Rhine to Mainz to the motorway junction Mainz.
History
The A 643 was built in 1966 and, together with the A 60 Mainz beltway. Planned the highway was also in the section from Wiesbaden to Taunusstein- Neuhof; this project was never realized until 417 to a portion of the highway.
Route
The A 643 starts in Wiesbaden out of the Schiersteiner road, which is in its complete course part of the federal highway 262. It crosses within the Hessian capital A66 at Schiersteiner cross, crosses the border to Rhineland -Palatinate on the Rhine and the Schiersteiner bridge leads to the high street Lenneberg past the Mainz district Mombach, crosses the nature reserve Mainz Sand Dunes and ends at the motorway junction Mainz in A 60th
Planned expansion
As part of the renovation and expansion of Schiersteiner bridge widening to Schiersteiner Cross and Rhineland- Palatinate page to a widening of the highway to the interchange of Mainz is also necessary to Hessian page. These costs for the six-lane expansion of the motorway, the motorway junction Mainz to Schiersteiner Cross were in 2008 estimated at 200 million euros.
From conservation organizations maintaining the four-lane expansion scenario involving the two hard shoulders in case of need, as well as landscape bridges was excited about the highway in the amount of existing ways of Mainz Sand Dunes Nature Reserve. To this end, a non-partisan and non-denominational alliance was founded. The coalition agreement of the red-green Rhineland- Palatinate Government of 2011 (Cabinet Beck V) was the goal of the partners defined to implement this model. To ensure that only the Schiersteiner bridge will be expanded six lanes. The distance between triangle and junction Mombach remains four lanes, the speed limit to be reduced from the current 100 to 80 km / hr. The area enjoys the highest protection at European level, as it is reported as FFH and EU as a bird sanctuary. The highway had split in two when it was built in the 1960s, the intact area.
Also the nature reserve Mombacher bank of the Rhine is affected by the possible construction as well. The meadows located there serve, inter alia, the white storks in the region as an important food biotopes. There needs to be made with the utmost consideration.
As a compensation measure for necessary by the development interventions in the valuable Weichholzauenbestand the Rettbergsaue the silted Altrheinarm the Schönborn Aue will be renatured before Geisenheim. To be built there a floodplain forest landscape with its typical floodplain vegetation.
On September 11, 2013, the official ground-breaking ceremony took place with the participation of Minister of Transport Peter Ramsauer.
Special
Although the motorway in Wiesbaden begins, the kilometer marker does not start at kilometer 0.0 but at 300.0 and then descends in the direction of Mainz.
The motorway junction Mombach is one of the few in Germany that are on a bridge. Since the Schiersteiner bridge was completed two years before the high street, the corresponding entrance and exit ramps were applied two-lane. The high street Lenneberg was completed and connected until 1964. These approaches and departures, however, were only equipped with very shortened acceleration and deceleration lanes, as both bridges were originally planned as a trunk road and built. For this reason, are located in this area also street lights and traffic control systems, which are no longer but since the mid- 1980s during operation.
Between the lanes on Wiesbaden page to a permanently installed speed measuring device ( flash) is located at km 297
In December 2012, the ADAC published a statistic in which the A 643 with respect to wrong-way drivers is one of the ten most dangerous highways. In the years 2010 and 2011 there were 23 times wrong-way driver messages on the short highway. 50 and the A 98 ( Weil am Rhein - Tiengen ) - In absolute terms, the A 661 ( Bad Homburg, Darmstadt) is 30 wrong-way driver messages before A 643 Extrapolated to 100 km per year resulting statistically 142.0 Wrong way driver messages and thus also " 3rd place". Hazardous according to these statistics are only the A 980 ( Waltenhofen AD - Allgäu ) with 156.9 and A 255 (Hamburg -Süd - New Elbe bridges ) with 166.7 statistical false driver reports per 100 km and year.
