Business leaders from eight towns and counties in the midlands and the west mett Minister for Transport Shane Ross to demand the Government honours its promises to upgrade the N4 and N5 national primary routes.
The Dublin-to-Sligo and Dublin-to-Westport roads are the last remaining ones that have not been upgraded to motorway status.
Members of the various chambers of commerce in the region say this is hampering economic development.
Business leaders from Donegal to Mullingar say the current state of the N4 and N5 is putting the northwest and west at a disadvantage in attracting foreign direct investment.
They want the N4 Dublin to Sligo motorway to continue with a dual carriageway from Mullingar to Rooskey in Co Leitrim.
They are also asking for a new bypass of Carrick-on-Shannon to be brought forward; improvements to the existing N4 route between Collooney and Castlebaldwin in Sligo and substantial improvements on the Dublin to Westport roa, between Longford town and the Ballaghdareen bypass.
