The Olympic and Paralympic Games transcend sport; they also act as catalysts for changes that improve the daily lives of millions of citizens in host cities. Paris 2024 is the most recent example, but London 2012 and, years earlier, Barcelona 1992 also marked turning points in accessibility, infrastructure and urban mobility.

The “Change Starts with Sport” programme and the celebration of the world’s third-largest sporting event triggered a major investment plan that has modernised the Paris public transport system. Before hosting the Games, the city faced significant accessibility barriers. The Olympic push reshaped that reality with long-lasting effects.

According to the City of Paris, 350,000 people with disabilities visited during the Games, and around 185,000 benefit every year from improvements driven by the event’s legacy.

A legacy in infrastructure and public transport

Since 2016, Île-de-France Mobilités —the authority responsible for coordinating transport across the region— has invested more than €2.4 billion in accessibility and comfort. As a result, 300 train and RER stations are now accessible, compared to 137 in 2015, covering 97% of passenger traffic. Among them is Saint-Denis Station, refurbished with €165 million to accommodate 27 million annual users.

The impact also extends to surface transport: all bus and tram lines are now accessible, with 59 bus routes, eight tramways and 1,750 adapted stops. More than 27,000 RATP employees assist passengers with disabilities daily, providing guidance and tailored support.

Improving everyday accessibility

The Olympic legacy goes beyond the rail network. In Paris, the number of accessible taxis has quadrupled to 1,000 vehicles. Adapted parking spaces increased by 20% to 5,400. In parallel, two to three additional stations are made accessible every month across the Île-de-France Mobilités network, while all new lines and rolling stock are designed under universal accessibility standards.

Urban projects also form part of the legacy. The Saint-Denis Olympic Village is being converted into a neighbourhood with private, social and student housing, offices and green spaces, designed for 6,000 residents and workers. The clean-up of the River Seine, supported by €1.4 billion, has returned the waterway to public use, with swimming areas scheduled to open in 2025.

Past examples of Olympic transformation

London 2012 delivered unprecedented urban renewal in the city’s East End. The former Athletes’ Village became the East Village, with 2,818 homes —1,379 of them affordable or social housing— plus a school, health clinic and commercial spaces. Facilities such as the Lee Valley VeloPark and the London Aquatics Centre were repurposed for public use, offering a velodrome, cycling routes and swimming pools for local communities.

Barcelona 1992 marked a turning point in the Catalan capital’s urban transformation. The Olympic Village was built in Poblenou, regenerating a degraded industrial zone and creating the city’s first residential area facing the sea. The waterfront was opened with parks, promenades and sports facilities, while key infrastructure including Barcelona Airport, the Estació del Nord and the Port of Barcelona was modernised and integrated into daily civic life.

The future of the Paris Metro

One of the greatest challenges remains the historic Paris Metro, more than a century old. By early 2025, 29 stations were fully accessible, including all 21 on Line 14 and eight on Line 11. The “Metro for All” programme, announced by Valérie Pécresse, President of the Île-de-France Region, aims to make the entire network accessible within two decades, with an estimated budget of €20 billion.

The plan foresees 68 additional accessible stations by 2031, supported by feasibility studies and a full mapping of the network. A dedicated committee brings together the Île-de-France Region, the City of Paris, RATP and the French State, alongside disability associations, to define concrete solutions. With works overseen by RATP, financing will be shared across all institutions involved.
