Lisbon’s Metro system will extend its operating hours on the Green and Red lines to 2:30 AM on both Saturday and Sunday nights, and Sunday to Monday night. This temporary schedule change is directly related to the ongoing Rock in Rio Lisboa music festival. The extended hours aim to facilitate transportation for festival attendees. The decision was announced today by the Lisbon Metropolitan. Regular Metro service will resume at its standard times outside of these specified dates. This is a common practice during large events to manage increased demand and ensure public safety. The extension provides attendees with a convenient and reliable way to travel to and from the festival grounds.
