Connecting Ireland will see extra routes in a bid to increase the number of people with access to at least three return trips daily.
More than 100 villages will benefit from the services and there will be 60 new connections to regional cities.
CEO of the National Transport Authority Anne Graham says there's an overall 57 million euro investment being made:
"70% of people in rural Ireland will have access to public transport service that provides at least three return trips daily to the nearby town. Over 100 rural villages will benefit from frequent public transport service for the first time and overall service levels will increase by 25% and service levels at local level that's our local link services will increase by 200%."
