The Montesson Toll Area: Everything You Need to Know About the A13 Motorway

Located close to Paris, the Montesson toll area is used daily by many motorists heading to the capital or joining the A14 and A13 motorways towards Caen. At certain times, this route can experience heavy traffic, leading to traffic jams and slowdowns at the tolls. To optimise traffic flow on the A14 and ensure motorists’ safety, Sanef and Bip&Go are transforming this route into a free-flow motorway. What does this system involve? How does toll payment work? Bip&Go answers your questions.

Montesson Toll Gate on the A14: Key Information

Situated in Île-de-France, in the north of Yvelines, the small town of Montesson is almost completely surrounded by the Seine. Bordering Carrières-sur-Seine and Chatou and situated close to Saint-Germain-en-Laye, Montesson enjoys an ideal location for easy access to the capital. This is why the A14 motorway runs through it, linking Paris to Orgeval and the A13. Montesson is the first toll gate on the A14, located at kilometre 8. The A14 and A13 motorways are the preferred routes for drivers travelling to Normandy, especially to Caen and Rouen from Paris. The Montesson toll area is therefore a strategic and busy crossing point, often subject to significant slowdowns due to traffic.

Montesson Toll Area: Moving to a Free-Flow System in 2024

Recognising the challenges faced by motorists and the hassle of possible traffic jams, the operator of the A13 and A14 motorways, Sanef, has decided to move away from traditional barrier tolls in favour of a more innovative system. First introduced in Norway in the 1990s, free-flow motorways represent the future of road mobility in France and across Europe.

The free-flow system allows motorists to drive on the motorway without stopping. Barrier tolls are removed to keep traffic moving smoothly. Overhead gantries are installed to detect vehicles and apply the correct toll charge. This identification is carried out using sensors that recognise the vehicle category and determine the amount owed. Cameras and antennas are also fitted to the gantries. Their role is to detect electronic toll badges or, if none is present, to photograph the vehicle’s number plate to assign payment to the correct driver. The transition to free-flow tolling on the A14 motorway will take place during 2024.

At traditional tolls, the badge is detected by sensors at the barriers in the dedicated subscriber lanes. On free-flow routes, antennas on the overhead gantries register your passage. The amount due is then automatically charged to your Bip&Go monthly bill.
