The Federal Highway 620 (abbreviated as BAB 620) - Short form: Highway 620 (abbreviated as A 620 ) - begins at interchange Saarlouis and runs on Völklingen and Saarbrücken over to the triangle Saarbrücken. The highway fulfills several functions: first, it serves as a portion of the connection between Luxembourg and Saarbrücken ( and from there to the A 6), for others it is a bypass route for many local through traffic along the middle Saar. In addition, the south- eastern section of the A 620 acts as a city highway for Saarbrücken. The A 620 is expanded throughout four lanes but absent for long stretches hard shoulder on both sides.
From the A 620 has a good view of the World Cultural Heritage Site is possible between junctions Völklingen - Geislautern and Völklingen center. The fact that the route in the city of Saarbrücken is almost exclusively in the formerly undeveloped floodplain, it is at a high water level of the Saar over 3.90 m between Bismarck and Wilhelm -Heinrich- Bridge regularly (about once or twice a year for at least two days ) were flooded. For this reason, A is in this area called 620 also jokingly tributary of the Saar with 13 letters ( = city highway ).
Architectural History
The construction work for this section were begun in 1961 and completed in 1963. The opening of the A 620 takes place on 14 December 1963 - to date, it was called B 406 On this day also, of the A 6 between St. Ingbert and Saarbrücken was opened to traffic. Younger castle wall of the Saarbrücken castle demolished and behind it, which dates from the medieval castle, free dug up at ground level, thus you won - In order to enable the construction of the A620 through the city of Saarbrücken in the Saarland along the front was 20 m area for the route. The hitherto tethering to the front wall Old Bridge had thus become " too short ", the newly emerged gap on the new highway was a steel pedestrian bridge ( popularly called "bottleneck" ) spans.
A curiosity was located between junctions Saarlouis - Lisdorf and Wadgassen: A formerly existing there temporary bridge over the highway made it necessary that the highway a tight corner combination had to follow and only allowed a maximum speed of 80 km / hr. As part of the renovation work because of the new connection of the B 269 ( Bous (Saar) / Ensdorf (Saar ), and France), this " harassment " since February 2007, no longer exists. At this point, the AS Ensdorf was completed with a new bridge over the Saar to the B 51 back and a tangent to the B 269, which runs in the direction About the Lord and continue across the border to France, in mid-2008. The specific plans for this already existed since the mid- 1980s.
Urban Future
Currently, there are plans to lead the highway in Saarbrücken in the range between Bismarck and Luis bridge through a tunnel. This has an urban, but also traffic engineering reasons: firstly, because of the regular flood closures, on the other hand, could the noise and fumes caused by the highway, will be banned in the tunnel and a new, as well as the official name, " city center by the river " arise. Through a tunnel, the closures could be largely avoided.
