The Saint-Sever Nouvelle Gare eco-neighborhood project is part of the dynamics of the realisation of the New Paris Normandy Line (LNPN) and responds to the dual problem of the current rail saturation of the Rive Droite station and the lack of tertiary attractiveness of the Métropole. The Saint-Sever Nouvelle Gare project is part of Seine Cité’s overall objectives: redefinition of a new centrality for the heart of Rouen metropolis, in complementarity with the eco-neighbourhood Flaubert and Luciline.This project is part of the project of the Métropole Rouen Normandie, and is transcribed in the SCOT and the PDU.The eco-neighbourhood project Saint-Sever Nouvelle Gare in Rouen is based on a close interlinkage of urban, economic and transport issues. The aim is thus to create the conditions favourable to the increase of metropolitan functions in the territory with the opportunity to develop a quality service offer, in rapid connection with Paris and its main decision-making centres. This multifunctional district, building on the current Saint-Sever district, provides for mixed programming with the presence of housing, tertiary economic activities, public facilities, attractive public spaces and alternative car travel. It will also include a strong connection to the new station and the creation of a multimodal exchange hub in order to obtain the best conditions of accessibility and mobility possible as part of the redefinition of metropolitan centrality.In view of the introduction of the new station by 2030, the existing district must be revitalised and changes in mobility behaviour in favour of active modes must be initiated now. Also, in this context, the Metropole Rouen Normandie plans to reconfigure, year after year, the public spaces of Rouen hypercentre on the left bank in order to promote the shopping center of the Seine and the bicycles of which the car is located. The design of the 1005 tram crossroads makes it possible to significantly expand the dedicated spaces for pedestrian and cycling crossings and to better connect the west of Avenue de Bretagne and the Brisout/Orléans district, east of Avenue and the Saint-Sever commercial centre. In particular, the development created a second previously non-existent pedestrian crossing. It reduces the urban cut-off effect caused by tram and road hoppers. The transition from conventional operation by lights to operation by STOP makes it possible to soothe traffic and affirm the priority of pedestrians.
