Traffic in the Lisbon district will face restrictions at the Túnel do Grilo, part of the IC-17 CRIL, for a 60-day period starting on a Monday. Infraestruturas de Portugal (IP) announced that the maintenance involves upgrading the lighting system within the galleries and near the tunnel entrances.

During the works, traffic will be limited to two lanes per gallery with a reduced speed limit of 50 km/h. Between 22:00 and 06:00, lanes will be closed, leaving traffic to flow through either two lanes or, in exceptional cases, a single lane.
