Barcelona is preparing for significant disruptions this Thursday, 11 September, as thousands are expected to take to the streets to mark the Diada de Catalunya. The large-scale demonstration, organised by the Assemblea Nacional de Catalunya (ANC), will affect traffic, parking, and public transport throughout the day.

The central gathering point is set for 3pm at Avinguda del Marquès de l’Argentera, adjacent to the Parc de la Ciutadella. At precisely 17:14 – a symbolic time referencing the year 1714 and the fall of Barcelona during the War of the Spanish Succession – the march will begin at Pla de Palau. From there, participants will advance along Passeig d’Isabel II and Passeig de Colom before reaching the Rambla de Santa Mònica around 8pm.
Traffic Restrictions
From 6am to 9pm, parking will be prohibited on several key streets, including Avinguda del Marquès de l’Argentera, Pla de Palau, Passeig d’Isabel II, Plaça Idrissa Diallo, and Plaça de Correus. Motorcycles will not be allowed to park on pavements in these areas either.
In addition, depending on the flow of traffic, exits 21 (both directions) and 22 (towards Llobregat) of the Ronda Litoral may be closed. Drivers are advised to plan alternative routes and allow extra travel time.
A full list of affected streets can be found here.
Public Transport Disruptions
Several bus lines will be disrupted throughout the day. From early hours, services on lines D50, H16, V15, V17 and 19 will be altered. From 3:30pm, additional changes will impact lines 47, 59 and 120.
The metro will experience heavy congestion, especially at Urquinaona (L1/L4), Jaume I (L4), Barceloneta (L4), and Drassanes (L3). Reinforcements of up to 20 extra trains – a 22% increase in service – are expected during the afternoon, particularly on lines L3 and L4. More details can be checked on the TMB official website.
Wider Context
The Diada de Catalunya is held annually on 11 September to commemorate the 1714 fall of Barcelona. While some see it as a cultural celebration, others use the date as a platform for political demands, particularly in support of Catalan independence.

This year’s march is anticipated to attract large crowds, making both participation and mobility planning crucial for residents and visitors. Local authorities recommend the use of public transport where possible and advise avoiding travel through the city centre by car.
