A huge road building project faces further delays following a critical report by a planning appeals body.
The A5, estimated to cost £1.2bn, would connect Londonderry to the border at Aughnacloy and improve access to Dublin.
Infrastructure Minister Nichola Mallon said she remains committed to progressing the scheme.
But it is delayed for new assessments on flood risk and its environmental impact, and possible alternatives.
It will be late this year before those assessments are done.
That will be followed by a reconvened public inquiry before the Planning Appeals Commission (PAC) in 2022.
