The Department of Seine-et-Marne has initiated significant works on the RD350 to create a cycle path and pedestrian walkway along this road. These developments are taking place between the towns of Gretz-Armainvilliers and Ozoir-la-Ferrière.
Initially, from October 16 to October 30, 2026, traffic will be alternating on the RD350 in the affected area. It should also be noted that railway works will impact traffic. Level crossing n°17, located between boulevard Aristide-Briand and boulevard Victor-Hugo, will be closed. A detour will be implemented to manage this closure.
Subsequently, from November 2 to December 19, 2026, the RD350 will be completely closed to traffic. This closure will affect the section between the town entrance sign of Gretz-Armainvilliers and the intersection with the D471. A detour will also be put in place during this period to ensure travel can continue.
The Department of Seine-et-Marne is committed to keeping residents informed about the progress of this major project for soft mobility in the area.
