District road M 3
The district road M 3 is a roughly 5.8 kilometers long connecting road in the northern district of Munich . It begins on Föhringer Ring on the municipal boundary between Unterföhring and Munich and ends in Aschheim on federal road 471 .
Course and development functions
The circuit road is two lanes in its entire course and is close to the base pyramid at the transition from Effnerstraße and Föhringer ring height free from the exterior Munich ring performed. It initially opens up the main access to the Munich North thermal power station and crosses the Munich East – Munich Airport railway line . The access roads to the Unterföhring industrial park with the headquarters of ProSiebenSat.1 Media and the Feringasee recreation area branch off from it . Shortly before it merges with the B 471 federal road, the Aschheim / Ismaning junction of the A 99 motorway ring has been on the M 3 since 2015.
history
With the relocation of Munich Airport, it was foreseeable that if the federal autobahn 9 north of Munich was overloaded, the state road 2053, which runs parallel to the autobahn, would be used as an alternative route to the airport and heavy additional loads were to be expected for its through traffic in Unterföhring and Ismaning. The M 3 district road was therefore built in the early 1990s to create a bypass connection between the north of Munich and the B 471, which - after the later expansion of the other roads - forms a western parallel to the Isar to the airport via sections of the B 388 and the B 301 . The route of the M 3 was routed south of the Mittlere-Isar Canal through agricultural areas with no nearby residential areas.
One of six permanent counting stations on district roads in the Munich district has been set up on the M 3 since 1992. Until 2011 it showed the following traffic load:

The link with the B 471 was initially set up as a level, traffic-light-controlled T-junction, which was a few hundred meters north of the Aschheim / Ismaning junction of the A 99, which was also on the B 471. From the south-east direction, it offered the shortest route from the motorway ring to the northern districts of Munich. When traffic was high, the capacity of the B 471 - M 3 intersection was often exceeded; this led to backlogs, especially in the morning peak with around 1300 vehicles leaving an hour, right up to the deceleration lane and the hard shoulder. Because the hard shoulder release set up in 2001 on the A 99 had to be deactivated during these phases, the crossing situation reduced the capacity of the entire section of the motorway in the direction of Nuremberg.
Construction of the junction to the A 99
Starting in 2008, the State Road Administration examined options for a more efficient link between the M 3, B 471 and A 99. Finally, it was decided to relocate the junction completely from the B 471 to the M 3 and to rebuild it as a full clover, the confluence of the M 3 to convert the B 471 into a roundabout and lead the main traffic from the M 3 to the B 471 to the north and vice versa with a bridge over the roundabout. In 2008 the costs were estimated at around 25 million euros. The plans were implemented from 2012 and the new junction was opened to traffic on October 16, 2015. The significant cost increases to 44.4 million euros in the end led to criticism in the district council of the district of Munich, which had to bear 18 percent of the construction costs.
Expansion of the roundabout in Unterföhring
With the increased capacity of the eastern connection of the M 3, the roundabout with the access to the Unterföhring industrial park became the new bottleneck in the course of the district road. In order to reduce the congestion in the morning rush hour traffic, the Unterföhringen municipal council decided in October 2015 to expand it with two bypass lanes.
