Bundesstrasse 312
The federal highway 312 (abbreviation: B 312 ) connects the A 8 at Stuttgart Airport with the A 7 near Memmingen .
From Filderstadt- Bonlanden, it runs a short distance together with the B 27 until just before the Aichtal- Aich Nord exit . At Metzingen it joins the federal highways B 28 and B 313 and leads through Reutlingen up the Echaz valley to Engstingen . There the B 313 branches off and the B 312 leads over the Swabian Alb to Zwiefalten , Riedlingen an der Donau and from there via Biberach an der Riss and Ochsenhausen to the Berkheim junction of the federal motorway 7 near Memmingen, where it merges into the B 300 .
The construction of the Reutlingen – Riedlingen section as state road no. 72 began at the beginning of the 19th century. Since 1811, the Reutlingen Regional Office has been working on the expansion of this road. With an expenditure of almost 40,000 guilders (florins), it expanded the Honauer Albaufstieg leading to the Alb, particularly in 1820, so that it could now also be easily accessed by the heaviest vehicles.
The long-term plan is to continue the federal highway 312 via a so-called Filder driveway from Stuttgart airport to the B 10 near Stuttgart-Hedelfingen . The section of the B 14 between the B 10 at the Gaisburg power station and Waiblingen was originally planned as the B 312. However, these plans were changed in late 1991 - a year before this section opened - and the section was rededicated.
In addition, the expansion of the B 312 in Upper Swabia between Berkheim and Biberach with the Edenbachen, Erlenmoos, Ochsenhausen and Ringschnait bypasses is still planned. Interestingly, the planning of the entire section is pre-financed by the district of Biberach, the cities of Biberach and Ochsenhausen as well as the IHK Ulm, as the federal government and the state of Baden-Württemberg are currently not providing funding for this due to other priorities. In this way, the parties to this pre-financing plan want the construction work to start as soon as possible.
In the Metzingen – Engstingen section, the Pfullingen bypass with the 1,180 m long Ursulabberg tunnel was opened in December 2003 . From 2009 to 2017, the Reutlingen bypass was built with the 1,910 m long Scheibengipfeltunnel , which opened on October 27, 2017. In the Lichtenstein area , a bypass with a simultaneous new construction of the Albaufstieg near Honau is being discussed, which can already be found in the urgent need of the current federal traffic route plan .
The route of the previously planned B 88 was largely identical to the B 312.
