The Liaison Verte, a 40 km route along the Yerres and Réveillon rivers, is undergoing maintenance and renovation to improve user safety and comfort.

The SyAGE is carrying out maintenance and renovation operations on the Liaison Verte, a major 40 km route connecting towns along the Yerres and Réveillon rivers. These interventions aim to preserve natural and architectural heritage while respecting local ecosystems and improving the living environment for residents.
Several projects are ongoing or planned. In Boussy-Saint-Antoine, the refurbishment of 100 meters of pathway will begin on September 21, 2026, lasting approximately six weeks, with a budget of €211,731.24 including tax. These works include the installation of 35 meters of guardrails, renovation of 110 meters of trail, creation of a 10-meter long wooden deck, and construction of a 25-step staircase.
Another project, starting on Monday, July 6, involves the renovation of 55 meters of pathway, the installation of new guardrails, and the refurbishment of about ten meters of wooden path. Lasting approximately three weeks, this project costs €95,000 including tax.
Furthermore, renovation work on wooden pathways took place in May 2026, costing €60,000 including tax. These interventions have helped to secure and preserve this popular amenity for walkers, maintaining its natural aesthetic through an identical oak repair over nearly 100 m².
The SyAGE reminds the public of the importance of respecting the signage in place to ensure everyone's safety during the works.
