Calendar of public transport projects in Ile-de-France

Here are the commissioning dates currently planned for the RER, metro, tram and bus projects on TZen's own site in Ile-de-France.

"The further we get from 2023, the more indicative the date is," says Ile-de-France Mobilités, where it is recalled that the work suffered several months of delays during the first confinement.

At the same time, the schedule is being revised for the Grand Paris metro (lines 15 to 18).

At the same time, the Société du Grand Paris estimates that the health crisis has caused "between three and eight months of delay depending on the lines" for the Grand Paris Express under construction around the capital.

She says she is committed to "limiting delays" and will announce "realistic" dates for commissioning "when the health crisis is behind us", a priori in the spring.

The first sections of lines 16 and 17 from Saint-Denis Pleyel to Le Bourget, announced in time for the 2024 Olympic Games, would thus be between three and eight months late, as would the following section of line 16 between Le Bourget and Clichy-Montfermeil.

Ditto for line 15 south of Paris, from Pont de Sèvres to Noisy-Champs, scheduled before the pandemic for summer 2025.

The 18 between Orly, Massy-Palaiseau and Saclay would be three to five months late compared to an opening scheduled for 2026/27.

The last section of the 16 between Clichy-Montfermeil and Noisy-Champs, scheduled for 2028, would also be between three and five months late, while that of the 17 between Le Bourget and the triangle de Gonesse, suspended by a court decision, is currently announced for 2028.

The rest of the 200 kilometers of the Grand Paris metro is planned for 2030.
