Viaduc de Gennevilliers

The Viaduc de Gennevilliers is a motorway bridge spanning just under a kilometer across the Seine, connecting Argenteuil and Gennevilliers. The structure was built as a dual-bridge system with adjustable center barriers that allow flexible traffic lane distribution.

The bridge was completed in 1974 and has served as a key transport link in the region since then. A retaining wall failure in 2018 prompted major repair work that strengthened the overall structure.

The bridge functions as a vital transport link for the north Paris area, shaping how thousands of commuters cross the Seine daily. It has become a necessary part of local routines for people moving between these two communities.

The bridge handles over 100,000 vehicles daily with lanes organized for different directions of travel. Traffic conditions can shift rapidly during peak hours depending on flow patterns.

The bridge uses a system of adjustable center barriers that shift lanes between two and three in each direction depending on time of day and traffic needs. This flexible design was created to handle the vastly different rush-hour volumes.
