The federal autobahn 99 (abbreviation: BAB 99 ) - short form: Autobahn 99 (abbreviation: A 99 ), also Autobahnring Munich - connects several freeways leading to Munich a few kilometers outside the city and enables long-distance traffic to bypass Munich.

The A 99 was already planned as a complete ring in the 1930s, but is not closed to this day. It runs from the A 96 in the southwest via the A 8 in the northwest and the A 92 in the north-northwest to the A 9 in the north (Munich-Nord motorway ring) and on to the A 94 in the east and the A 8 / A 995 in the south ( Munich-East motorway ring).

When did the section from Lochhausen to the Munich-North intersection come? In one piece?

Planning from 1963 with much closer management around the city of Munich

Due to the Second World War , construction was only started in places, the clearest evidence of the construction activities at that time is the Allach-Untermenzinger route , which can be clearly seen in aerial photographs, together with the remains of the route for the cross with the BAB 8; a bridge on the site that was never used was only demolished in the mid-1990s. There are also cleared forest sections north of the Hasenbergl .

After the war, the section between the München-Nord cross and the München-Süd cross (old name: Kreuz Brunnthal) was built in the mid-1970s. The A 8 Munich – Stuttgart was provisionally connected to the A 9 via the B 471 . Until then, long-distance traffic had to drive through the urban area of ​​Munich.

The Munich- Fröttmaning- Nord junction was built later to accommodate the additional traffic from the Allianz Arena to and from Stuttgart. It is only designed as a half connection point . The Aschheim / Ismaning exit was also built retrospectively - a few years after the section between A 9 (Munich– Nuremberg ) and A 8 (Munich– Salzburg ) had been completed to relieve the community of Aschheim from through traffic. However, this was only partially successful.

On February 18, 2006, with a ceremony, a continuation from Munich- Lochhausen to the Germering -Nord junction was put into operation and opened for public transport from February 19, 2006, after another section up to the A 96 at the Munich-South motorway triangle West went into operation at the end of November 2005. The A 99 ends here today.

The A 99 was originally built with six lanes. It now has four lanes in each direction between exit 12a (Munich-Neuherberg) and Kreuz München-Nord; In addition, between Kreuz München-Nord and Kreuz München-Süd, four lanes per direction of travel, including the hard shoulder, whereby the hard shoulder is released when there is high traffic. The motorway is also to be expanded to eight lanes between the München-Nord junction and the Haar junction. The section is divided into three planning sections. For the first section between AK München-Nord and AS Aschheim / Ismaning, the planning approval decision was issued on January 14, 2013. The entire expansion should cost 147 million euros. The expansion was completed on November 22, 2019.

Traffic volume

In 2015 there were a total of fifteen automatic counting points along the A 99. In west-east direction or clockwise, the average daily traffic volume during this period was:

Counting point	Motor vehicle traffic / day	Heavy traffic / day
AS Germering-Nord (N) (9219)	77,359	6,510
AK Munich-West (N) (9220)	61,433	5,413
AD Munich – Eschenried (O) (9774)	-	-
AD Munich – Allach (O) (9775)	119,880	16,992
Feldmoching (9155)	118.120	14,216
AD Munich-Feldmoching (W) (9216)	-	-
AD Munich – Feldmoching (O) (9207)	80,550	11,968
AK Munich-North (W) (9215)	82.205	9,673
Aschheim – West (9218)	122,586	18,370
Aschheim / Ismaning (S) (9211)	127,312	18,310
AK Munich-East (N) (9212)	118,793	17,345
AK Munich-East (S) (9213)	112,290	13,214
Neu-Keferloh (9244)	95,558	12,679
Hohenbrunn (9228)	96,420	13,929
Ottobrunn (9229)	87,152	15,540

With up to 120,000 vehicles per day (as of 2010), the A 99 is the busiest motorway in Bavaria. In 2015 there are already 160,000 vehicles per day and a further strong increase in traffic is expected. Traffic jams are particularly frequent in front of the Munich North, Munich South, Feldmoching, Eschenrieder Spange, Aubinger Tunnel and Allacher Tunnel motorway junctions (usually twice a day).

Construction progress / planning status

A 99 between the Kirchheim exit and the München-Ost junction, looking south

A ring closure in the south from the A 96 to the A 95 and on to the Munich-Süd junction (or to the A 995 near Unterhaching ) was included by the federal government in the Federal Transport Infrastructure Plan in 2003 as a project in further need with a high ecological risk. In October 2004 it was decided to delete the project from the federal transport infrastructure plan. In May 2006, however, a feasibility study was commissioned. Their estimated costs of around half a million euros were shared by the federal government and the Free State of Bavaria.

On November 26, 2008, the Southern Bavaria Motorway Directorate presented interim results of the study. A second interim report followed on April 29, 2009. Of the 95 route variants originally considered, only eleven remain. The lengths of the routes vary between 13 and 35 kilometers. The southernmost route variant runs south of Gauting, Baierbrunn and Oberhaching. Since large parts of it would have to be built underground, the construction costs would add up to 45 million euros per kilometer. Conventionally built kilometers of motorway cost around eight million euros.

In the last step of the feasibility study, it should be examined what effects the proposed routes would have on the environment, spatial structure, traffic and construction costs. On May 17, 2010, the Southern Bavaria Motorway Directorate presented the final report of the study. The presentation of the report comes to the conclusion that "when taking into account the measures to avoid and reduce interventions ... closing the gap in the motorway ring is basically sensible and feasible". In the final report, a planning recommendation is made for two of the originally examined routes. Both routes connect the Munich-South-West motorway triangle with different sections of the A 995 at Unterhaching and Taufkirchen. Both routes provide for tunneling under the village of Krailling with the Würmtal. Depending on the route, a tunnel under the Isar Valley together with Grünwald and Pullach or a tunnel a little further north is planned. The cost of both routes is estimated at 1.2 billion euros.

The continuation of the A 99 is politically controversial. On June 15, 2010, the then Bavarian Prime Minister Horst Seehofer stopped the project.

The A99 between the Munich-North motorway junction and Aschheim / Ismaning was expanded from 2017 to 2019. Preparations for the provisional traffic management had already begun in 2016. The release took place on November 22, 2019; the total cost of the expansion is given as 170 million euros. In the course of 2020, the possibility of activating the hard shoulder should also be created.

particularities

Eschenried clasp

A structural feature is the Eschenrieder Spange - often also referred to as "A 99a" - a four kilometer long branch of the A 99 that leads to the A 8 towards Stuttgart.

Aubinger tunnel

The Aubing Tunnel is the longest with its 1956 meters of Bavaria highway tunnel. It was recognized by the ADAC as one of the safest tunnels. In 2008 the tunnel received one of the most modern speed control systems in Europe at the time. The measurements are taken in both directions of travel without the driver noticing anything. 500 meters after the entrance, measuring points have been set up in both directions, which forward the measured data directly to the police. In the first week after its launch, more than 1,500 speeding violations were recorded, according to press releases.

Truck checkpoint

Between the Hohenbrunn and Haar junctions, in the direction of Nuremberg / Stuttgart, there is a truck control point for the police and the Federal Office for Goods Transport . Before the control point, the axle loads of the trucks are measured by sensors in the lane of the motorway in order to check the gross vehicle weight. Suspicious trucks are then waved out at the checkpoint; There is a calibrated scale with which the exact weight can be determined.

Trivia

As of January 1, 2016, the responsibilities for the A 99 were as follows:

• in the area of ​​the Munich-South-West motorway triangle with the A 96 (4/35) and the Munich-North motorway junction with the A 9 (13/72) at the Munich-North / West motorway maintenance authority,
• in the area of ​​the Munich-North motorway junction with the A 9 and the A 995 (13/72) and the Munich-South motorway junction (21/95) at the Hohenbrunn motorway maintenance office.
