The Police Service of Northern Ireland (PSNI) will provide support to the Garda Síochána (Irish police) in securing a significant European Union (EU) summit taking place in Dublin this week. Despite foreign officers not being involved in frontline policing, they are being assisted by PSNI, Latvian and Portuguese law enforcement agencies, among others. This operation, set to be the biggest in the history of the Republic of Ireland, comes amidst a series of hoax bomb threats. The EU Presidency has been held by Ireland since July 1st and will continue until December 31st. Garda Commissioner Justin Kelly acknowledged that the upcoming days would be challenging but expressed confidence in their preparedness.

As part of the operation, some 50 international leaders are expected to attend meetings at the Convention Centre Dublin, leading to considerable travel and traffic disruption. The public is advised to anticipate traffic congestion, with significant disruptions expected from Tuesday, November 10th, through Friday, November 13th. Arrivals and departures for these events will take place at Dublin Airport and Casement Aerodrome. Traffic restrictions will be implemented across the wider Dublin region to facilitate security motorcycle escorts. The M50 motorway and Dublin Port Tunnel are not anticipated to be directly affected.

Political leaders will be arriving and departing from Dublin Airport on November 11th, 12th, and 13th, with the highest impact during specified timeframes. Traffic restrictions will also be in place at Dunboyne between R108 and R122, while additional police patrols will be stationed along perimeter roads of Dublin Airport. The Casement Aerodrome at Baldonnel, an Irish military airbase, will see heads of state or government arrive and depart during the same timeframe, with the highest level of disruption expected.

Luas operations are set to continue as usual on November 10th, 2026, although there will be no east/west traffic on North Wall Quay from November 10th through 13th. The 3Arena will remain outside the security cordon for this operation; however, there will be no east/west traffic on North Wall Quay during the specified dates. Luas operations and access to the 3Arena will continue as normal, but travelers are encouraged to allow extra time during peak hours.
