The Requalification Pont du Lion in Saint-Genis-Pouilly, France, epitomizes a creative endeavor to redefine the city's entrance while enhancing safety and accessibility for both vehicular and pedestrian traffic. The existing stone bridge spans over the Lion River, serving as a crucial thoroughfare at the gateway to the agglomeration near CERN and Geneva. With a roadway width of approximately 7 meters and a span of 17.5 meters, the bridge forms a pivotal part of the Rue de Genève, aligning with ongoing urban renewal efforts.

The project aims to harmoniously integrate modern functionality without compromising the bridge's historical integrity. Key design objectives include creating a unified and visually cohesive image that marks the city entrance, revitalizing the natural promenade along the Lion River, and enhancing the overall sense of place. To achieve this, the proposal emphasizes wider pedestrian paths of at least 2.20 meters on each side, ensuring safe and comfortable passage for all users, including disabled individuals.

Central to the design concept is the integration of dissymmetric balconies and extended balustrades, which not only provide functional benefits but also enhance the aesthetic and experiential qualities of the bridge. By extending the balustrades beyond the bridge limits and introducing dynamic lines and surfaces, the Pont du Lion project creates a vibrant visual impact that complements the natural surroundings and encourages contemplation.

Moreover, the Requalification Pont du Lion project minimizes disruption to traffic flow during construction by employing innovative structural solutions. A central steel beam and transversal cantilever steel beams support the extended balconies, allowing for phased construction while ensuring continuous access along Rue de Genève. This approach underscores the project's commitment to practicality and minimal environmental impact, enhancing both functionality and visual appeal.
