N28 Carr's Hill Gets Temporary 60km/h Speed Limit for Year-Long M28 Works
Temporary 60km/h speed limit on N28 Carr's Hill from 15 Oct 2025 for one year during M28 motorway works. Allow extra time for your commute.
Motorists using the N28 Carr's Hill route will face a year-long 60km/h speed restriction from Wednesday, 15 October 2025, as major construction work on the M28 Cork to Ringaskiddy Motorway Project gets underway.
Cork City Council has issued a Road Works Speed Limit Order under Section 10 of the Road Traffic Act 2004, reducing speeds across multiple sections of the busy corridor to accommodate the significant infrastructure project. The temporary measures will remain in place until 15 October 2026.
The council says the reduction, which will see current 100km/h and 80km/h limits dropped to 60km/h across affected stretches, aims to "increase the safety of both the workforce and commuters" during construction.
Where the Changes Apply
The speed restrictions will affect six key sections of the N28 and its slip roads around Carr's Hill, between Rochestown Bridge and the Carrigaline Road junction.
Both the northbound and southbound mainline sections between Rochestown Bridge and 550m south of Carr's Hill Bridge will see speeds reduced from 100km/h to 60km/h. The northbound off-slip to the R855 Carrigaline Road will also drop to 60km/h.
Drivers joining the N28 southbound from the Carrigaline Road R855 on-slip, as well as those merging from Maryborough Hill onto the northbound carriageway, will face the new 60km/h limit where 80km/h previously applied.
The Mount Oval off-slip section heading towards Ard Keale Road will similarly be restricted to 60km/h.
A Year of Patience Ahead
For Cork commuters already familiar with the congestion around Carr's Hill, the year-long restriction may test patience, but it reflects the scale of work needed for the M28 motorway upgrade. The project represents a major step in improving connectivity between Cork city and Ringaskiddy Port, though drivers can expect disruption as the price of progress.
The order was signed by Valerie O'Sullivan, Chief Executive of Cork City Council.
Motorists are advised to allow extra time for journeys and observe the temporary speed limits, which will be clearly signposted throughout the affected sections.
