From March 3 to 14, 2025, the A14 freeway will be closed in both directions between Nanterre (Hauts-de-Seine) and Orgeval (Yvelines), every night from 9:30 pm to 5 am. Maintenance work will cover the entire length of the expressway.
The entire route of this expressway will be affected, mainly due to work on one of the tunnels along the way. In addition, specific work on the Chambourcy interchange is scheduled for the nights of March 10 to 12, 2025, resulting in the temporary closure of the Poissy and Orgeval interchanges.
The work does not stop there. Sanef will take advantage of these night-time interruptions to dismantle the toll equipment at the Chambourcy interchange and remove the toll canopy. These operations are part of a wider project to transform the Paris-Normandy axis into a free-flow road, in order to improve traffic flow.
In view of this closure, alternative routes have been put in place to limit the impact on traffic. Motorists will be able to take the RN13, RD913 orA86, depending on their direction of travel. We strongly advise you toplan ahead and consult traffic information platforms such as Sytadin to monitor traffic conditions in real time.
This work, although restrictive, aims to modernize the road and improve user safety. During this period, drivers travelling in the evening and early morning will need to be vigilant and patient.
