Pont-Audemer - Autoroute A13 SAPN

How can motorways be developed and respond to new societal challenges? The free-flow motorway is a real response to the need for fluidity on a high-traffic axis, and for modernization towards sustainable mobility. Successfully deployed in many countries, this transformation of the motorway will allow drivers to travel at the authorized speed, without slowing down or stopping, to pay the toll.

Free-flow motorway, how does it work?

Free-flow technology allows the customer to use the entire motorway axis without a physical toll barrier, thanks to sensors allowing the detection and identification of vehicles, without reducing their speed.

How does it actually work?

  • Metal frames or "gantries" spanning the roadway are installed along the axis. Customers can thus pay their toll without needing to stop there.
  • These gantries equipped with intelligent sensors detect each vehicle and identify its category (car, truck, etc.) using devices that calculate its volume, profile and number of axles. These sensors are interconnected and cover all lanes of the motorway regardless of traffic conditions (nominal, lane change, congestion, etc.).
  • Antennas make it possible to detect the electronic toll badge of Bip&go subscriber customers at 130 km/h (for light vehicles) or 90 km/h (for heavy goods vehicles).


How to pay the free-flow toll?

Automatic payment

  • Do you have a electronic toll badge ? No changes thanks to the badge valid on all motorways!
  • Don't have a badge? In your Sanef customer space, you can activate automatic payment at each visit. In just a few clicks, register your vehicle's license plate and your method of payment, before the trip.

Payment after the journey(s)

  • You can pay online, or at Sanef/Sapn partners, within 72 hours after your visit, by mentioning your plate of registration.

What are the benefits for customers?

The free flow is a big step forward to improve the journey of our customers:

  • + fluid and + fast: no need to stop to adjust your passage. A real time saver in periods of heavy traffic, especially during long weekends or major holiday departures.
  • + simple: a single payment for the entire journey and no longer at each toll station.
  • + security: less stress when approaching and leaving the toll barrier, no need to find the right line when approaching the toll and choose your payment method.
  • + responsible: less fuel consumed during journeys, less CO2 emissions into the atmosphere.

An ambitious project, supported by all Group employees

The transformation of the motorway into free flow is a global and cross-functional project involving the entire Sanef/Sapn collective. It is an ambitious project, which the group carries with pride and commitment to respond even better to its public service mission.

  • New, more diversified professions (manual verification of license plates, information on the device, customer assistance for payment, collection, etc.)
  • The continuity of the digital transformation of our Group
  • Better working conditions: end of night work for a better balance between professional and personal life, end of outdoor work for better safety...
  • To develop in these new professions with confidence, employees will benefit from training and personalized support in order to be operational on the day of commissioning.

Free-flow motorway on our network

Since 2014, the Sanef group has been involved in a program to modernize tolls. Sanef's "free flow toll" solution saw the light of day for the first time in France at the Boulay toll on the A4 motorway.

In 2024, the 210 km of the Paris Normandy motorway will adopt free flow technology.

Deploying free-flow toll collection: a strategic project for our Group

Choosing free flow on the A13 and A14 motorways means embarking on a major transformation, with changes to our customers' payment habits and profound changes to our organisations and businesses.

The project will have an impact in a number of areas:

  • Technological: with the deployment of new vehicle detection equipment.
  • In terms of our infrastructure: with the removal of toll barriers and the reconstruction of the new motorway route.
  • In human resources: with the transformation of business lines, the need for new resources and the creation of a new dedicated customer relations centre.
  • In our information systems: in particular with the deployment of new online payment tools.

By leading us to completely rethink the historical toll model, the implementation of free flow is also leading all our teams to redefine the relationship we want to build for and with our customers.

This project goes far beyond the 210 km of the Paris-Normandy route. It gives new meaning to our public service mission.

The Paris-Normandy free-flow route: a first in France?

The deployment of free flow over the 210 km of the Paris Normandie route (A13 - A14) is the first major project to transform a historic motorway in France.

On a smaller scale, free-flow tolling has already been installed:

  • In 2019, on our network to the east of Metz, at junction 36 at Boulay Moselle (A4).
  • In 2022 in the Allier region, on the 88 km of the A79 motorway newly built by the APRR group.

And elsewhere in the world?

Although free flow is a recent development in France, it has been a reality for several decades in many countries. Norway was the first country to adopt this system in 1991. It now equips the motorways of around twenty countries (Chile, Costa Rica, Brazil, the United States, Australia, Japan, Portugal, etc.) on every continent, and most often coexists with the traditional toll barrier model.
