The SNCF has long sought to improve the station to better handle traffic, particularly following the expansion of high speed rail services during the 1990s and 2000s accompanied by rising passenger numbers. By 2015, 700,000 passengers were using the Gare du Nord each day; projections produced in 2018 predicted these numbers to rise to 800,000 by 2024 and 900,000 by 2030. During 2015, the architect Jean-Michel Wilmotte was engaged by SNCF with the directive to "open the station towards the city". According to SNCF Project Director Stéphane Cougnon, the programme has a budget in excess of 600 million euros (£526m). The endeavour has the public backing of Paris' mayor, Anne Hidalgo, who has also pledged to address the frequent traffic problems in front of the station by reconfiguring its approaches. Critics of the redevelopment have included several architects and urban planners, who have typically objected to the high level of commercialisation involved.
