Franchissement Pleyel, Transportation bridge in Saint-Denis, France

Franchissement Pleyel is a 300-metre bridge by architect Marc Mimram crossing 48 railway tracks of the Paris-Nord network and the Landy depot in Saint-Denis. It is 20 metres wide and rests on three intermediate piers built between February 2021 and June 2023. On the west side the pedestrian deck splits into a Y, one branch curling over Kengo Kuma's Saint-Denis Pleyel station. Three inhabited structures are planned: a café-concert, an urban-furniture structure and a station-garden giving access to RER D.

Marc Mimram won the 2016 competition against four teams, including Rem Koolhaas's Arcadis/OMA. The three intermediate piers were built between February 2021 and June 2023, and the pedestrian deck opened on 16 May 2024, before the Olympic Games. The road section is planned for 2026, with the full cost re-estimated at 240 million euros in 2023.

The bridge's name comes from the Pleyel district, and its deck is designed as a belvedere over the railway tracks. Three inhabited structures were planned along it: a café-concert, an urban-furniture structure and a station-garden giving access to the RER D. The jury in 2016 praised the generous public space and its animation by these structures.

The bridge accommodates pedestrians, cyclists, and buses with good connections to metro line 13 and RER D. Visitors can access the space anytime and will find plenty of room to walk and stay.

The deck spans 48 tracks of the Paris-Nord station network and the Landy technical centre, which is why it reaches about 300 metres. Three intermediate piers were built between February 2021 and June 2023. On the west side the walkway splits into a Y, one branch curling over Kengo Kuma's Saint-Denis Pleyel station to keep the slope gentle for wheelchair users.
