Yvelines: A13 disruption this April 2026

Work on the former Buchelay toll plaza in Yvelines is disrupting traffic on the A13 throughout April 2026. Temporary lanes, reduced speed limits, and closed on-ramps are in place until April 24, 2026. What to expect and what are the alternatives? Here’s everything you need to know.

Regular users of the A13 motorway in the Yvelines will need to adjust their habits this April 2026. Work continues at the site of the former Buchelay toll booth, whose barriers were removed in March 2025 as part of the shift to free-flow traffic on the A13. From April 13 to 24, 2026, traffic will run on temporary lanes, with a 90 km/h speed limit in this stretch of the Yvelines. A project to watch closely if you’re planning to hit the road this month, whether heading toward Paris or toward Caen.

Which A13 on-ramps will be closed in April 2026?

According to Sanef, the schedule for ramp closures is as follows: the Mantes-Ouest ramp (No. 13) will be closed in the province-to-Paris direction in two phases, from April 13 to 17, and then from April 20 to 22, 2026. The Mantes-Sud ramp (No. 12) will be closed from April 20 to 24, in the direction toward Caen. Work will run from 10 p.m. to 5 a.m. to limit traffic disruption. Detour routes are in place for each closure. Be sure to check the Bison Futé app before hitting the road to adapt your trip in real time.

What alternatives to avoid traffic jams on the A13?

No need to panic: there are several options to bypass the work zone or simply leave the car in the garage for the duration of the works. On the road, the A14 from Poissy offers a different route to reach Paris, while the RN13 provides a local alternative for nearby travel around Mantes-la-Jolie, though it can quickly become congested during rush hours. For journeys toward Paris, the A12 via Saint-Quentin-en-Yvelines also presents a fallback route to consider depending on your starting point.

For those looking to ditch the car, the J line of the Transilien links Mantes-la-Jolie to Paris-Saint-Lazare in just over an hour, with frequent departures. It’s a comfortable option, especially during the spring break period when highway traffic can be particularly fickle. Timetables and real-time tracking are available on the SNCF Connect site. Carpooling via BlaBlaCar Daily is gaining traction in this part of the Yvelines and can prove to be a practical, cost-effective solution for home-to-work commutes.

A13 motorway works in Yvelines to continue until 2027

This isn’t a project that will wrap up overnight. These April works mark a new phase in reshaping the site, notably the destruction of peripheral tracks and then the buildings of the former toll plaza. The completion of the works tied to the free-flow toll system is not expected before 2027. In the meantime, the area will undergo a landscaping overhaul with fertile soil and plantings. A welcome green redevelopment for this corner of the Yvelines that we often speed through without really stopping.
