The N28 road between Rochestown and the Carr’s Hill Interchange will close for three days starting July 24 to facilitate infrastructure works on the M28 Cork to Ringaskiddy Project. According to local officials, the closure requires heavy goods vehicles to divert through Carrigaline town centre, while car traffic will follow separate signed routes to maintain connectivity.
Why is the N28 closing?
The closure is a required step in the construction of the M28 Cork to Ringaskiddy Project, which aims to improve regional safety and transit efficiency. Local councillor Jack White confirmed that the project includes the demolition and replacement of the existing Maryborough Bridge. To maintain traffic flow during this long-term replacement, which is expected to span 9 to 12 months, crews will install a temporary bridge alongside the current structure.
How will the diversions affect Carrigaline?
The diversion strategy splits traffic based on vehicle size. While passenger cars will follow a route that rejoins the N28 near Carr’s Hill, heavy goods vehicles face a significantly longer path. According to project briefings, HGVs heading to and from Ringaskiddy must travel via the Cork Airport Road, through Fivemilebridge and Ballygarvan, before passing directly through the centre of Carrigaline to reach the Shannonpark Roundabout.

This redirection is expected to cause a temporary increase in HGV traffic through the town’s main streets. Residents are advised by local authorities to expect higher congestion levels during the weekend of the works and to plan for additional travel time.
Infrastructure upgrades and regional connectivity
The M28 project represents a significant shift in how Cork manages its port-related logistics. By modernizing the link between Cork city and Ringaskiddy, the project seeks to move freight traffic away from local town centres in the long term. Comparing current transit patterns to future projections, the M28 is designed to serve as a high-capacity bypass, reducing the reliance on the existing N28, which currently acts as a primary artery for both commuters and heavy freight.
