Portuguese police (PSP) have announced traffic restrictions around the Tejo Park in Lisbon on June 20th, 21st, 27th, and 28th due to the Rock in Rio Lisboa music festival. These constrictions are expected to impact roadways in the vicinity of the event venue. To accommodate festival attendees, the Lisbon Metro will extend its service hours until 2:30 AM on those dates. The PSP advises motorists to anticipate delays and plan alternative routes during the festival period. This measure aims to manage the increased traffic flow associated with the large-scale event. Organizers anticipate significant crowds, necessitating the coordinated traffic and public transportation plan. The extended metro service is intended to provide a convenient transportation option for attendees.
