The National Development Plan - Project Ireland 2040 - will commit to expenditure on capital projects totalling more than €165 billion. Here is a look at the impact on the Galway and the West.
Minister for Public Expenditure and Reform Michael McGrath has said a number of road projects will get the go ahead despite the Government's commitment to spend twice as much on public transport.
The controversial Galway Ring Road is one of the major road developments listed under the National Development Plan.
The project will be assessed based on climate impact and priority across the country.
The minister said road projects provided for in the NDP and committed to by Government are not all ready for construction and are at different stages of the planning process.
In addition to Dublin, the four cities of Galway, Cork, Limerick and Waterford are listed for future investment under the NDP.
Minister McGrath said a panel of external experts will oversee the process and projects will be subject to intense financial scrutiny.
Green Party leader Eamon Ryan outlined what he described as the "transformation of the west of Ireland", with the development of the under utilised Western Rail Corridor.
He said he envisaged a rail network going all the way from the quays in Waterford to Limerick Junction with access as far as Ballina.
He also cited the former Athenry to Claremorris line as an example of a link up which he said would be so much more than just a section of railway line for commuters.
He said an inland rail freight port in a place like Limerick junction would form part of what he described as a low carbon future.
The Taoiseach said the Government would "enthusiastically" support expenditure for the Western Rail Corridor going forward.
