Which Sanef motorways are affected by the free flow?
Free-flow toll collection is a major innovation on French motorways. This system, with no barriers or stops, allows users to travel more smoothly and quickly, while ensuring reliable toll collection. The Sanef group is one of the first to deploy this technology on its network. But in practical terms, where are the free-flow gantries installed?
Free-flow tolling is already operational on several routes on the Sanef network. Here are the main areas concerned::
- The A13 motorway between Paris and Normandy has been completely switched to free flow.
- The A14 motorway, which extends the A13 to the west of the Paris region, is also equipped with gantries.
- Exit 36 off the A4, near Boulay-Moselle, is a regional zone that also uses this system.
On these sections, the old physical tolls have been dismantled and replaced by detection gantries placed above the lanes.
Where are the free-flow toll gantries placed?
The gantries are located at strategic points, generally where the old toll plazas used to be. They are equipped with advanced technology:
- High-definition cameras for reading number plates
- Sensors for electronic toll badges
- Vehicle classification systems
This equipment identifies each vehicle, calculates the fare to be paid and operates without touching or stopping. All without slowing down traffic.
How do I pay after borrowing a free-flow section?
You have two options:
- With an electronic toll tag: payment is automatic, just like at a conventional tollbooth.
- Without a badge: you must pay for your journey within 72 hours on the sanef.com website.
- No need for a ticket or barrier: your number plate is recognised and your passage is recorded.
In brief
- The Sanef free flow is active on the A13, A14 and exit 36 of the A4.
- The gantries replace traditional tolls and detect vehicles automatically.
- Payment is automated or available online within 72 hours of the visit.
- The aim of this system is to ensure a smoother flow of traffic
