Donegal County Councillors have called for more time to make their decision on Preferred Route Corridors for the Ten T Network.
Representatives were due to confirm a decision on the preferred routes this week.
However, a number of elected representatives sought extra time to consult with landowners on the project.
The TEN-T Network in Donegal is a scheme of improvements on three routes: the N15/N13 Ballybofey / Stranorlar Urban Region, the N56/N13 Letterkenny to Manorcunningham and the N14 Manorcunningham to Lifford / Strabane / A5 Link.
Some of the biggest concerns about the road upgrades are rooted in the Twin Towns, where residents and business owners fear the proposed bypass will affect local trade. They are calling for a link road from the Route Corridor to preserve the commercial life of Ballybofey and Stranorlar.
A number of public consultation events were hosted by Donegal County Council in recent months to hear opinions on the Emerging Preferred Route Corridor.
The preferred routes were brought before the council on Monday, but councillors agreed to defer any decision-making on the plans to a special sitting on Thursday 24th April.
The Holy Thursday meeting will also consider a report by the Standards in Public Office Commission on Cllr John O’Donnell.
