Griffeen Avenue closed for emergency drainage works ahead of school start

Emergency Drainage Works Begin on Griffeen Avenue

Urgent surface water outfall works have commenced in the Griffeen area under the Clonburris Stage 2A Joint Infrastructure programme. The South Dublin County Council has authorised emergency road closures to facilitate the installation of a deep storm water sewer crossing, ensuring public safety before the new Griffeen Community College welcomes its first pupils.

Clonmel Enterprises, the appointed main contractor, is executing these heavy civil engineering tasks which include installing 1050mm diameter precast concrete pipes. A primary concern was managing the interaction with approximately 600 students due to start their term on 24th August. To mitigate risks associated with heavy plant traversing the school access road and navigating the roundabout, an emergency closure has been scheduled.

The works are set to begin on 12th August and will last for five days over the weekend. The Griffeen Avenue section between Grange Castle Road and Griffeen Road will be closed to allow the installation of the upgraded storm outfall within the designated red boxed area shown in project imagery.

To manage traffic flow, a diversion route via Castle Road and Griffeen Way has been planned. Variable messaging signs will be erected in advance to inform motorists, and Traffic Management Plans have been submitted for approval by the council. Furthermore, the road will be thoroughly swept before work begins to ensure all entrance and exit points are free of debris, prioritising the safe egress and access for the returning school community.
