The Bridges and Roads Authority has announced the start of its biennial tunnel cleaning campaign, beginning Monday. This routine initiative includes maintenance of safety installations alongside cleaning activities.

To minimise disruption to traffic flow, the majority of the work will be conducted during nighttime hours. The project is scheduled to continue until early June. Over the coming weeks, a total of 25 tunnels will undergo partial closures as part of the maintenance campaign.
