[F] A709 Montpellier 

This seems a great way to separate long-distance, through traffic from dense local traffic. This would be ideal for other cities and large urban areas that have adjacent motorways carrying through traffic; for example, in the UK where there is a break in the east-west M62, north of Manchester, where Liverpool to Leeds and Hull traffic shares very busy lanes with the M60 orbital motorway of Manchester: this stretch is crying out for a Montpellier style solution!

Nice, it reminds kind of the A4 near Reims. Although the old autoroute there simply cut Reims in two. The new southern version of the A4 goes much farther from the Reims city limits. This setup at Montpellier is kind of strange as the expanding city will grow and start to enclose the old and new A9 quite rapidly.
