Échangeur de la porte de Bagnolet

The Échangeur de la porte de Bagnolet serves as a massive concrete knot where the Boulevard Périphérique meets the A3 motorway. It consists of multiple levels of interlocking loops and slip roads designed to manage high volumes of traffic entering Paris from the east. In the early nineteen seventies, architects carved this structure into the dense urban fabric, displacing hundreds of residents. Today, the gray, sweeping curves remain one of the most prominent gateways for commuters entering the city every morning.
