🚧 GRIFFEEN AVENUE ROAD CLOSURE – ANSWERS FROM SDCC
I followed up directly with SDCC management to get clarity on a number of questions residents have been asking regarding the upcoming closure at Griffeen Avenue.
I’ve now received detailed responses which I’m sharing in full below so everyone has the same information. 👇
✅ Why the works are being treated as an emergency road closure
🚶♀️🚲 Confirmation that pedestrian and cyclist access will be maintained
🚌 Update on engagement with Dublin Bus and other public transport operators
🚧 Details on advance warning and diversion signage
➡️ And importantly, my request for an additional advance diversion option before Kishoge Roundabout will now be reviewed by the contractor.
With Griffeen Community College due to open on 24 August and approximately 600 pupils expected SDCC has advised that the closure is being accelerated to complete the high-risk section of drainage works before school traffic begins.
I appreciate residents will be concerned about the impact on traffic so I felt it was important to get these questions answered and the information out as early as possible.
📎 I’ve included the full replies from SDCC management below.
Please share with anyone who may be affected by the closure.
Dear Cllr O Toole,
See replies to the queries raised.
QUESTION Can you confirm why these works are being classified as emergency road works rather than a planned road closure?
REPLY While the drainage outfall works form part of the wider Clonburris Stage 2A infrastructure project, the road closure is being sought as an emergency measure to protect public safety and road users. The project team identified a significant safety risk associated with the installation of a deep surface water sewer crossing of Griffeen Avenue, which requires heavy construction plant and materials to traverse the school access road and roundabout. Given the imminent opening of Griffeen Community College on 24 August, with approximately 600 pupils expected to attend, it was considered necessary to accelerate and complete this particularly high-risk element of the works before the school opens, thereby eliminating potential conflicts between construction activities and school traffic. The emergency closure is therefore being proposed as the most effective mitigation measure to protect the public and road users.
QUESTION Will the closure apply to all road users including pedestrians and cyclists or will pedestrian and cycle access be maintained across the works?
REPLY Pedestrian and cyclist access will be maintained but will be restricted to one side of the road, initially the new school side, before switching over once the road crossing has progressed. Please see the attached Traffic Management plan sowing cycle track and footpath remaining open in each phase.
QUESTION Have Dublin Bus and other public transport operators been notified well in advance and will the diversion arrangements be reflected in their timetables journey planners and apps?
REPLY The Contractor engaged with the bus operators ASAP once the emergency road closure became necessary. The site team are in frequent contact with the public transport operators and expect them to update their systems and apps in line with the information provided.
QUESTION Could you provide a breakdown or map showing where the advance warning signs variable message signs and diversion signage will be located?
REPLY Please see the image below which is also included in the attached PDF
QUESTION Finally, could consideration be given to placing an advance diversion sign before the Kishoge Roundabout for traffic travelling northbound on the R136? This would allow motorists the option of turning left onto the Adamstown Link Road before reaching the closure rather than continuing and becoming caught in congestion. I believe this would provide a useful alternative route for many residents on that side of Lucan and improve traffic flow during the works.
REPLY; The Contractor will review the installed signs and make extra provisions as suggested.
Regards
Cllr Liona OToole Peace Commissioner
