M28 Update: New Maryborough to Carr’s Hill Link Road to Open Next Week
New Maryborough to Carr’s Hill Link Road opens next week as M28 works continue, with a new Carr’s Hill layout and blasting near Shannonpark.
A new link road between Maryborough and Carr’s Hill is due to open to traffic next week. It is one of the bigger milestones so far on the M28 Cork to Ringaskiddy motorway project. A new road layout at Carr’s Hill will come in at the same time.
The latest M28 progress update, published on 13 November 2026, says the new roundabout arrangement at Carr’s Hill will open alongside the link road. Motorists are being asked to follow all temporary signage and take care in the area while they get used to the new layout.
Controlled Blasting Near Shannonpark
Rock excavation using controlled blasting has started again in a cutting north of the Shannonpark Roundabout. Bridge deck works at the nearby Shannonpark structure are progressing, and the deck concrete pour is planned for the coming week.
Rochestown
Work continues on the retaining wall along the verge of the N28 off-ramp to Rochestown, ahead of kerbing and road surfacing. The first section of the bridge column at the new structure has been poured. Backfilling around the foundation will follow, with the aim of reopening the southern footpath on Rochestown Road by the end of next week.
Until then, the south side footpath stays closed and pedestrians are asked to use the north side. Traffic management also remains in place at the junction with the N28 on-ramp for road widening and adjustments to the approach roads. The N28 off-ramp to Rochestown is still running with a single lane.
Bus Stop 242081 (Rochestown Rise) has been moved a short distance west to make room for construction. The temporary stop will stay in place for a number of months.
Advance Notice: N28 Lane Shift
In the coming weeks, traffic lanes on the N28 at Rochestown will move eastwards for the next phase of construction. Advance warning signs will go up before the change, and road users are advised to allow extra time for journeys.
Mount Oval and Maryborough Hill
Excavation for drainage and utility ducting continues on the Mount Oval off-ramp. Flagmen will work intermittently on the slip road to manage plant crossings.
At the new Maryborough Hill Bridge, the east abutment foundation is due to be poured next week. Excavation for the west abutment will begin shortly after that.
Board of Works Road, Rock Road and Shanbally
The wing walls at Board of Works Road are finished and backfilling is ongoing around the new structure. Motorists should expect machinery to cross the road from time to time.
At Rock Road, the existing road has been lowered to suit the future alignment, and crews are getting ready for kerbing and surfacing. Temporary traffic lights remain in operation and there will be intermittent plant crossings.
In Shanbally, work continues on the new structure at Marion Terrace and on the retaining wall running east from it.
Other Traffic Management
On the L2473 and R611, kerbing and drainage installation is ongoing ahead of the next phase of road surfacing. Traffic management also stays in place along sections of the R611.
Flagmen are managing plant movements during working hours on the R855 and the R609 (Carrigaline Road), and also on Ballinrea Road. At Cogan’s Road, flagmen and temporary traffic lights will operate at times during working hours while machinery crosses.
