Progress Update
20th March 2026
Dear <>,
Work on the project is progressing steadily.
In the Rochestown area, work on the retaining walls beside the N28 off‑ramp is advancing well, with road‑widening operations extending from the Bloomfield junction also underway. Sheet pile extraction in this section has been rescheduled and will now take place from next week.
Further along the route, preparations for the new Mount Oval off‑ramp are progressing, with excavation for the new slip road due to begin in early April 2026.
Meanwhile, excavation for the Maryborough to Carr’s Hill link road is ongoing, and construction of the retaining wall has now commenced. This area will remain a focus of activity for several months as these works advance.
On the Board of Works Road, excavation and early construction activities for the new bridge have started and will continue over the coming months.
At Shannonpark, the new link road works will remain active throughout the next month. The bridge structure in the Shannonpark area is also progressing, with the north abutment works ongoing and construction of the south abutment now underway.
Traffic Management
To support ongoing construction, several traffic management measures remain in place or will be introduced shortly. On the Rochestown off‑ramp from the existing N28, a lane closure continues, with one lane remaining operational for the next couple of weeks to accommodate retaining wall works.
At Mount Oval, traffic management measures are in effect to facilitate controlled plant crossings associated with the slip‑road works. On Maryborough Hill near the bridge, daytime traffic management will be in place for one day next week, with two‑way flow maintained throughout. Looking ahead, further traffic management—such as stop/go controls and temporary signals—will be required in April to allow service diversions in the same area. Additional information will be provided in the next newsletter.
Two new site access points along the N28, between Carr’s Hill and Maryborough Hill, will become active next week. In addition, the existing N28 climbing lane between Rochestown and Carr’s Hill will close from early April for approximately six months, reducing the route to a single lane in each direction. The lane closure beneath the Carr’s Hill underbridge is now in operation and will remain in place for several months.
Traffic management continues along the R855 and R609 (Carrigaline Road), both east and west of the N28, where flagmen manage plant crossings during working hours—operations which remain weather‑dependent. Similar intermittent flagman‑controlled crossings are in place on the Board of Works Road.
A new site entrance and exit will also become operational from the existing Shannonpark roundabout, providing improved access to the works area. Additionally, the R611 (Cork Road) will switch onto a newly constructed section of road in April (See Shannonpark Area TM Image below). Flagmen remain active on Ballinrea Road during working hours, and traffic management is in place along the R611 verge.
Finally, road users travelling through the Shannonpark area are asked to proceed with caution and follow updated signage, as changes to road alignments will begin next week.
There will be no rock excavation by means of controlled blasting in the coming weeks.

Ringaskiddy Urban Realm
Loughbeg
The main focus of works continues to be at Loughbeg and Ringport. Surfacing works at the tie-ins and within the business park are nearing completion. The brick paving of the roundabout central island is 95% complete.
Mainline Works
Fencing and landscaping works are also nearing completion throughout the scheme. The crash barrier and environmental noise barriers are fully installed. Final commissioning of the street lighting is ongoing.
Excavation for the construction of 2 no. CCTV columns and 2 no. ITS gantries was carried out this week, which will be followed by construction of the reinforced concrete bases and associated works.
Barnahely Roundabout
The footway/cycleway works on the east side of the R613 in Barnahely are due to be complete by the end of this week. By the middle of next week this area will be fully opened to pedestrians/cyclists and the traffic management will switch to the western edge of the road, either side of the Johnson & Johnson entrance.
The M28 Project Team wishes to acknowledge and thank all road users for their continued patience and cooperation during these works.
