There will be severe disruption to traffic and public transport with road closures across the capital due to the 45th running of the Dublin Marathon.

The first wave to take off will be the wheelchair participants at 8.40am from Leeson Street.

Several waves of other competitors will start their runs at intervals up to 9.45am.

Multiple road closures came into effect around the start and finish lines in the city centre at 6am yesterday morning and will remain in place until 8pm tonight.

Dozens of additional road closures along the marathon's route in the city centre around Merrion Square and St Stephen's Green will begin at 3.30am, with staggered end times throughout the day.

As the marathon follows its route out of the city centre and into the north and south suburbs, rolling road closures will come into effect throughout the morning. These closures will be lifted between 10.30am and 8.30pm.

Transport for Ireland has advised public transport users to take note of the disruption while Iarnród Éireann warned that there will be no Dart service between Grand Canal Dock and Bray due to major works.

Dublin Bus said the following routes will be affected by the marathon: 15a, 15b, 19, 23, 24, 4, 7, 7a, 11, 11b, 13, 14, 15, 16, 27, 37, 38, 38a, 39, 39a, 44, 47, 52, 56a, 60, 65, 65b, 68, 69, 70, 74, 77a, 80, 82, 99, 150, 151, C1, C2, C3, C4, E1, E2, F1, F2, F3, G1, G2 and S2.
