Union Quay to Close for Five Weeks as Trinity Bridge Works Begin
Union Quay closed 28 July-29 August for Trinity Bridge flood defence works. No left turn from Copley Street. Plan alternative routes through city centre.
A major section of Union Quay will be completely closed to traffic for over a month from Monday as essential flood defence work begins on Trinity Bridge, affecting one of Cork city centre's key routes.
Both lanes of Union Quay between South Terrace and Copley Street will be closed from Monday 28 July until Friday 29 August 2025 as part of the Morrison's Island Public Realm & Flood Defence Project. The five-week closure will significantly impact traffic flow through the city centre during the busy summer period.
The closure means drivers will no longer be able to turn left from Copley Street onto Union Quay, though a right turn towards the School of Music will remain available. This change will force many drivers to seek alternative routes through an already congested city centre.
Alternative Routes Available
Motorists needing to access South Terrace and George's Quay can take a right turn from Anglesea Street at the junction with Infirmary Road. Cork City Council has confirmed that advance warning signage will be installed ahead of the closure, with clear diversion route signs to guide drivers around the affected area.
The Trinity Bridge works form part of the broader Morrison's Island Public Realm & Flood Defence Project, designed to improve flood protection for the city centre while enhancing the public spaces around the island. The project represents a significant investment in Cork's infrastructure and flood resilience.
Vehicle access from Copley Street will be maintained for those heading towards the School of Music via right turn, ensuring the Conservatory of Music and Dance retains accessibility during the works period.
The timing of the closure during the summer months may help reduce some traffic disruption, as school traffic is typically lighter during the holidays. However, visitors to Cork and regular commuters should plan alternative routes well in advance of the 28 July start date.
Cork City Council has thanked the public for their patience during the improvement works, which are expected to deliver long-term benefits for flood defence and public amenities in the Morrison's Island area.
