Bank holiday travellers should prepare for significant disruption this weekend as the Dublin Marathon brings widespread road closures and Irish Rail carries out works affecting several DART routes. The changes will affect drivers, bus passengers, rail users, sports fans and day-trippers across Dublin.
What is happening this bank holiday weekend?
The Dublin Marathon, now in its 45th year, is expected to attract approximately 22,500 participants, along with large numbers of spectators. Road closures and bus diversions will be introduced around the race route, with arrangements beginning on Friday at Merrion Square South, where the marathon finishes.
At the same time, planned railway works will restrict DART services during Saturday, Sunday and Monday. Irish Rail passengers are being advised to check their journey before travelling and allow additional time for connections.
Breaking News: DART services affected by line works
No DART services will operate between Grand Canal Dock and Bray, or between Howth Junction and Howth, across the three-day period. These closures mean that passengers travelling between central Dublin, south Dublin and Howth will need to consider alternative arrangements.
The restrictions are particularly important for people planning to attend the marathon, visit Dublin city centre or make coastal trips during the bank holiday. Passengers should consult Irish Rail for the latest timetable information before setting out, as replacement transport and revised operating arrangements may vary by route.
- DART services will not operate between Grand Canal Dock and Bray.
- DART services will not operate between Howth Junction and Howth.
- The disruption is scheduled for Saturday, Sunday and Monday.
- Passengers should allow extra time and check official Irish Rail updates before travelling.
Dublin Marathon road closures and bus diversions
The marathon will create temporary restrictions across parts of Dublin as runners move along the course. Roads near the finish area at Merrion Square South will be among the first affected, with further closures and traffic management measures expected along the route.
Bus services may be diverted, delayed or required to stop short of their usual destinations. The impact will depend on the timing of the race, local traffic conditions and the movement of spectators. Public transport is likely to be a more practical option than driving into central Dublin, although rail users must account for the DART closures.
Drivers should avoid making unnecessary trips through the city centre during the busiest periods. Anyone travelling to hospitals, workplaces, accommodation or planned events should check access arrangements in advance.
Who is most likely to be affected?
The disruption will be felt by several groups, including:
- Marathon participants and spectators: Race access points and viewing areas may be reached more easily by walking or public transport.
- DART passengers: Direct services will not be available on two sections of the network.
- Motorists: Temporary road closures and diversions may increase journey times.
- Bus passengers: Routes operating near the course may face diversions or delays.
- Day-trippers: Popular coastal destinations, including Bray and Howth, may require more detailed travel planning.
How to plan your journey
A few simple steps can reduce the risk of being delayed:
- Check Irish Rail information before travelling, particularly if your journey includes the DART.
- Review Dublin road closure and bus diversion notices before driving into the city.
- Leave earlier than usual and build time into any onward connection.
- Consider walking between nearby destinations where practical.
- Do not rely on a normal weekend timetable during the marathon and bank holiday period.
Passengers should also keep their plans flexible. Conditions can change during large public events, especially if crowd levels, traffic volumes or operational requirements alter throughout the day.
Why the disruption matters
The weekend highlights the importance of coordinating major sporting events with public transport and road infrastructure. A large marathon requires extensive traffic management, while planned rail works are used to maintain and improve the network. When both take place at the same time, the combined effect can be greater than either event alone.
For residents, the main concern is reaching work, appointments or family commitments. For visitors, the challenge will be understanding which routes remain open and whether a planned journey can be completed without changing trains or buses.
What happens next?
Travel conditions will develop as road closures are introduced and the marathon progresses. Irish Rail passengers should rely on official service information for the most current details, while motorists and bus users should check Dublin traffic notices before departure.
The most reliable approach is to plan around the affected DART sections, avoid unnecessary driving near the marathon course and allow extra time for every stage of the journey.
