The Federal Highway 99 (abbreviated as BAB 99) - Short form: Highway 99 ( Abbreviation: A 99 ), also orbital motorway Munich - connects several leading to Munich motorways a few miles outside the city and enables the long-distance transport, the bypass of Munich.
The A99 has already been configured in the 1930s as a complete ring is not closed today. He leads from the A96 to the southwest via the A 8 in the north-west and the A 92 in the north - northwest to the A9 to the north ( Beltway München-Nord ) and on to the A94 to the east and to the A 8 / A 995 in the south ( orbital motorway München-Ost ).
Formation
Due to the Second World War began with the construction only partially, the clearest evidence of the former construction activities is based on aerial photographs clearly recognized Allach sub Menzingerstraße - line along with remnants of the course for the cross with the BAB 8; never used a bridge on the site was demolished until the mid- 1990s. Furthermore, deforested sections of forest just north of Hasenbergls. After the war, first the section between the intersection München-Nord and the intersection München -Süd ( Old name: Kreuzbrunn Thal ) was built in the mid-1970s. The A 8 Munich -Stuttgart was provisionally connected via the federal highway 471 to the A 9. Until then, the long-distance traffic had to drive through the city of Munich.
The junction München -Nord - Froettmaning was subsequently constructed to accommodate the extra traffic to and from the Allianz Arena in Stuttgart. It is merely designed as a half junction. The exit Aschheim / Ismaning was also later - a few years after the completion of the section between A 9 (Munich -Nuremberg ) and A8 (Munich - Salzburg) - built to relieve the town of Aschheim from through traffic. However, this is only partially successful.
On 18 February 2006, taken to the junction Germering North in operation and opened to public traffic on February 19, 2006, after a further section to the A96 at the motorway junction Munich South West with a ceremony a continuation of Munich- hole Hausen end of November 2005 went into operation. Here ends the A99 today.
Planning
Ring closure
A ring circuit in the south of the A 96 to A 95 in the south west and continue to the junction Munich South (or the A 995 at Sauerlach ) was not recorded in 2003 by the federal government in the Federal Transport Infrastructure Plan. Nevertheless, it was given in May 2006, about one million euros expensive feasibility study, in which the federal government took over half the cost.
On 26 November 2008, the Directorate of Highways, southern Bavaria presented an interim study results. On 29 April 2009 a second interim report followed. Of the originally contemplated routes 95 variants are now only eleven remained. The lengths of the lines vary in this case 13-35 kilometers. The southern route runs south of Gauting variant, Baierbrunn and Oberhaching. Since large parts of it would have to be built underground, the construction cost would amount to up to 45 million euros per kilometer. Conventionally built motorway miles cost about eight million euros. In the last step of the feasibility study will now be examined what impact the proposed routes on the environment, spatial structure, transport and construction costs will have.
On 17 May 2010, the General Directorate of Highways southern Bavaria presented the final report of the study. The presentation of the report comes to the conclusion, that ' in principle useful and feasible in light of the measures for the prevention and reduction of interventions ... closing the gap of the ring road " is. In the final report, a planning recommendation for two of the original studied routes is given. Both routes connect the motorway junction Munich South West with different sections of the A 995 in the amount Unterhaching or Taufkirchen. Both routes provide for the tunneling of the village Krailling with Würmtal. Depending on the route of a tunnel under the Isar valley with green forest and Pullach or a little further north extending tunneling is also provided. For both routes cost of 1.2 billion euros are estimated.
The continuation of the A99 is politically controversial. On 15 June 2010, the Bavarian Prime Minister Horst Seehofer stopped the project.
Extension
The A 99 is considered with an average of 120,000 vehicles per day as the busiest highway in Bavaria. Congestions are often especially before the highway crosses the Munich-North and South. The A-99 was originally built six lanes. She now has between exit 12a (Munich - Neuherberg ) and intersection München-Nord four lanes in each direction; also between Kreuz München -Nord junction Munich South, involving the breakdown lane four lanes in each direction, in which case the hard shoulder will be released at high traffic. The highway will be expanded achtstreifig Since 2013 between AK München-Nord and AS Ascheim - Ismaning. On this route the green stripe in the middle is wider. The section is divided into three sections planning. For the first section between the intersection Munich -Nord AS Aschheim / Ismaning the zoning decision was adopted on 14 January 2013. The entire development is expected to cost 147 million euros.
Special
A structural feature is the Eschenriederspange - often referred to as "A 99a " - a four- kilometer-long tributary of the A99, which leads to the A8 direction Stuttgart.
The tunnel is the longest Aubinger with its 1956 meters of Bavaria highway tunnel. He was awarded by ADAC as one of the safest tunnel. The tunnel also has one of the most advanced speed control systems in Europe. In both directions the measurements are carried out since early March 2008 without the driver noticing them something. Every 500 meters after the entrance are decorated in both directions stations that transmit the measured data directly to the police. According to press releases In the first week after the launch have been recorded more than 1500 speeding.
Between the junctions Hohenbrunn and hair in the direction of Nuremberg / Stuttgart, a truck inspection post of Police and the Federal Office for Goods Transport. The axle loads of trucks are measured to check the permissible gross weight of trucks over sensors in the pavement of the highway before the inspection body. Striking truck then herausgewinkt at the checkpoint; there is a calibrated scale, with the exact weight can be determined.
