Portique free flow de Boulay (57) sur l'A4

On the A4 motorway at Boulay near Metz,

, the two existing toll plazas have been replaced by two free-flow tolling gantries.

They are equipped with lasers, cameras and signals in order to:

  • detect and classify vehicles,
  • read vehicle number plates,
  • and record transactions.

Commissioning is planned for the beginning of 2019.

The Sanef Group has put forward to the French government a broader roll-out of free-flow tolling in completed sections of motorways.

This innovation will ensure:

  • Reduced congestion thanks to more freely flowing traffic, heightened appeal for the regions through which the motorways pass,
  • A motorway that is more in tune with its customers’ current methods of payment,
  • Increased safety for customers and all people working on the motorway,
  • A more environmentally-friendly motorway that creates savings*:
    • millions of hours of driving,
    • hundreds of millions of litres of fuel,
    • tens of millions of KWh,
    • millions of tonnes of CO₂,
    • less light pollution, areas given back to nature
