The Ronda de Dalt (B-20) is experiencing significant delays, with queues reaching 12 kilometers heading towards Llobregat. This congestion impacts the entire city stretch and extends to El Prat and Sant Boi.
The Ronda Litoral (B-10) is also heavily affected, reporting 10 kilometers of slow-moving traffic towards the Nus del Llobregat, complicating access to the L'Hospitalet venue.
Major highways including the A-2 and B-23 are reporting delays between 8 and 10 kilometers. Additionally, an accident on the C-32 near L'Hospitalet has further worsened the situation during peak morning hours.
