The A5 upgrades could get underway in 2024.
Northern Ireland's Infrastructure Minister says it's a deliverable project, despite ongoing legal objections.
The road, which is the main corridor between Dublin and the northwest, has been hit by numerous delays since first being announced in 2007.
Since then, the infrastructure project has been hit by planning errors and three legal challenges led by the Alternative A5 Alliance, largely made up of landowners.
Speaking to Northern Sound News in Clones, John O'Dowd said he defends people's right to object but upgrades are needed for road safety:
The southern part of the project on the N2 is split into two sections, with funding for the stretch from Clontibret to the border being shelved by the government.
Minister O'Dowd said he has no say on the project beyond Aughnacloy but would co-operate with them if it meant getting the road completed.
