The Franchissement Pleyel is one of the most defining structures of the Paris 2024 Olympics. It consists of a bridge and a 300-meter pedestrian walkway designed by French architect Marc Mimram.

The project will create a public space in the heart of Paris that serves as both a functional connection and a lively area for transit and gathering. The Franchissement Pleyel spans the rail tracks of Gare du Nord near the Stade de France station in Saint-Denis. The first component is a road bridge connecting Rue du Dr. Finot on the west to Avenue François Mitterrand on the east. The pedestrian walkway will branch into two paths on the west side, providing direct access to the Saint-Denis Pleyel station.

The activity involves verifying the executive design (prepared by the appointed designers) through a “parallel” design process (external review). This required the development of highly accurate computational models, comparable to those used in executive design. The walkway model features a fully modeled deck with approximately 80,000 plate elements, while the inhabited structures (“Bubbles”), longitudinal fibers, and transverse arches are modeled with beam elements. The project will require over 8,000 tons of steel, manufactured by Maeg Costruzioni Spa.
