CARRIS flags route changes on 17 September for buses 735, 731, 738, 755, 764 and 768

What happened

Lisbon bus operator CARRIS has published a service notice titled "735, 731, 738, 755, 764, 768 | Alteração de percurso 17.09.2026" — that is, an announced change of route on 17 September 2026 affecting six bus lines: 735, 731, 738, 755, 764 and 768.

The notice appears on CARRIS's own service-changes page in the "Viaje" (Travel) section of its website. The short summary attached to the notice simply directs readers to the page for the full information, and the notice itself does not state the nature or extent of the route change in the text supplied here. No publication timestamp was included in the information available.

Because the notice is dated 17.09.2026, the change is tied to that date rather than to an immediate, same-day disruption.

Why it matters for international residents

CARRIS is the municipal bus and tram operator in Lisbon, and these six lines form part of the day-to-day network used by many residents and commuters across the city. A route change — "alteração de percurso" — means buses may run along a different path from the one printed on older timetables, stop lists or route maps.

If you regularly use one of these lines, the practical effects can include:

• stops no longer being served, or served in a different order;
• a different walking route to your nearest stop;
• connections to metro, tram, train or other bus lines that no longer line up as before.

For international residents who have learned a fixed routine — the stop around the corner, the connection that works — an unannounced change can mean missed appointments, longer school runs, or a longer walk home. It is also relevant to anyone who has only recently arrived and is still building a mental map of the network, since printed or saved information may no longer match what the bus actually does from 17 September.

What to do next

• Open the CARRIS service-changes page linked below and read the full notice for lines 735, 731, 738, 755, 764 and 768, rather than relying on the short summary.
• Check whether any stop you use is on the affected lines, and whether it is still served after the change.
• If you depend on one of these lines for a regular journey (work, school, medical appointments), plan an alternative in advance and allow extra time on the first days after the change.
• Re-check the notice closer to 17 September 2026, in case CARRIS publishes further detail on the same page.
