Périphérique de Toulouse

From the point of view of its name, it is made up of two branches linking the A61 and the A62 autoroute, one passing to the south and west of the city (A620, old western ring road), the other passing to the east (A62-A61, former eastern ring road).

It is therefore no longer the branch (east or west) that defines the nature of the ring road but the direction of traffic.

For signaling purposes, a specific logo has been created for the signaling of the exits allowing entry to the ring road: it refers to the directions of traffic (outer or inner ring road).

Initially limited to 110 km/h and 90 km/h respectively, the vehicles first had to reduce their speed by 20 km/h during the summer of 2006: the metropolis and the prefecture, together with the air observatory in Midi-Pyrénées, had set up a speed limit to reduce emissions of exhaust gases and polluting particles produced by vehicles.

Renewed for the summer of 2007,[2] this decision was finally made permanent on 4 October 2007.
