The arrival of the new town center of Montigny marks the end of the model of XXL commercial zones. Construction began in Juneon the Patte d'oie d'Herblay, alignment of large brands over 5 km along the RD14.

By 2030, 800 to 900 homes, shops, a medical office, a nursery, a park and a school must be built on 750 m of this axis. “This commercial area is losing its attractiveness,” says the mayor.
