 The French government has not yet designated any of the lanes as high-occupancy vehicle lanes, however.The Francilienne is the third Paris ring road, enclosing the A86 "super-périphérique", which in turn encloses the Périphérique.Enclosing the Francilienne itself is the very large 1100km long, and incomplete outer ring named the Grand Contournement, the south-eastern portion of which has yet to be constructed as of 2019.
