A86 autoroute

The A86, also super- périphérique or Périphérique de l' Ile -de -France, is a ring road around Paris ( ring closure in January 2011).

At a distance between 8 km and 16 km from the central point Notre Dame, the route goes around with a few corners to Paris. It forms the second ring between the congested inner ring motorway Boulevard Périphérique and the proposed outer ring road francilienne on the outskirts of Ile- de -France. The ring road with 78 km total length is completed, the last 10 km long section in the western part leads there as " duplex" car tunnel the tracks over each other.

History

The planning of the ring roads around Paris was 1960-1965 under the project PADOGG ("Plan d' aménagement et d' organization générale de l' agglomà parisienne "). However, the former plans for the A86 encountered resistance at the residents who appealed for numerous appeals to potential emissions of noise and fumes. Construction began in 1968 then sections that belonged to the National Road 186. At the time of the oil crisis of the construction, however, were reinstated.

Only later the closure was driven to a motorway ring. Until 1994, the A86 led to cuts of 50 km in length from Nanterre La Courneuve, from Bondy to Thiais and Antony to Versailles. Connectors were in the Val -de- Marne ( for example, the tunnel of Chevilly -Larue ), and in the Hauts -de -Seine between Nanterre and Rueil -Malmaison and between Seine- Saint- Denis and Bobigny. Until 2000, the motorway route extended to 64 km in length and with the opening of the connection Rueil-Malmaison to A13 to end of June 2009 grew stretch of motorway at 69 km. It remained the piece between the A13 and Pont- Colbert ( Jouy -en- Josas ), originally estimated to be (partially ) e opening in 2010, the completion of works moved to 2011.

Since the A86 has long been plagued congestion during rush hours, the expansion of the third ring road of francilienne is being driven.

Special

The western part of Rueil-Malmaison to A13 is designed as a toll tunnel "Duplex A86 ". Since the end of June 2008, the 4.7 km passenger tunnel is opened, in which in a tube, the carriageway leads to two levels above the other. Each tunnel section has been executed with a height of 2.55 m and two lanes plus an emergency lane - only cars with a maximum height of 2 meters, while trucks and motorcycles must not use the tunnel. Later, the car tunnel is to be extended by the A13 to Pont- Colbert to a total of 10 km. A second tunnel for trucks and other vehicles will Rueil- Malmaison directly (without exit to the A13 ) over 7.5 km of the A12 to the west connect, from where you can go to the southern part of the A86 via the N12 again. The car tunnel shortens the travel time from 45 minutes to 10 minutes and is the only toll road to the A86 - a large-scale bypass offers over the western location, A14, A12 and N12.

Other tunnels are located in Bobigny and Antony. For the latter had an underground aqueduct to be destroyed, which was built for Catherine de Médicis in 1610 - an information board at the south end, the motorist out.

In the eastern part of the route of the A86 runs on a section between Nogent -sur -Marne and Joinville- le -Pont, together with the A4. Since in this common portion only 4 lanes in each direction were available ( the A4 leads a three -lane carriageways, the A86 dual carriageway ), this "bottleneck" has developed into a stagnation point. By 2005, one further track has been added, but these are released only as needed, also there are plans to increase the standard of development of the common portion permanently.
