Road renovation in Clamart

The Razel-Bec Île-de-France Ouest agency teams carried out a road redevelopment project on Avenue Claude Trébignaud in Clamart, in the Hauts-de-Seine department. The objective was to renovate and transform this urban corridor by accommodating new mobility uses while improving environmental performance.

The project included reducing the carriageway from four lanes (2×2) to three lanes, constructing a 4-metre-wide greenway separated from the road by a landscaped strip, installing drainage trenches, and strengthening the existing pavement structure. Work began in September 2025 and was delivered with a high level of execution, enabling the cycle path to be completed ahead of the contractual schedule.
