Ten new counties will benefit from new or enhanced bus routes around towns and villages.
More services will be available in areas like Athlone, Trim, Longford and Dundalk.
For example, Limerick will be connected to Ballybunion, Mitchelstown, Scariff and Cashel.
Minister of State at the Department of Transport, Hildegarde Naughton, described new rural bus routes as “absolutely necessary” ahead of their launch on Sunday.
Rural Ireland has traditionally suffered from a lack of public transport and Minister Naughton said the new routes would go some way towards correcting the imbalance.
“Also, there’ll be new enhanced routes linking the Midlands to the northeast - linking areas like Dundalk and Ardee, Drogheda and Trim and Athlone to Longford.”
The Government hopes it will convince people to travel by bus to college or work, thereby boosting low carbon travel and reducing emissions.
“For example, there’ll be a direct route to the University of Limerick and those then between the age of 19 and 23 can avail of their 50% discount with their young adult card.”
