Ireland West and Donegal Airports will benefit from an 8 million euro funding package being allocated to regional airports over the next four years.
The Minister for Transport says the money will boost safety and security while helping airports reach their carbon reduction targets.
Overall, 7.9 million euro will be divided between Shannon, Ireland West, Kerry and Donegal airports.
Shannon will receive 1.9 million for a new security perimeter fence and a replacement tender for the fire service there.
2.8 million euro of the funding will go towards projects at Ireland West including a body scanner, an upgrade to the electrics and an automated weather observing service.
€367,000 has been allocated under the Regional Airports Programme for Donegal Airport.
The funding will support investment in safety and security, alongside projects with a sustainability focus.
Transport Minister Darragh O’Brien says the funding supports “connectivity and balanced regional development, while seeking to maximise the use of existing capacity”.
