Concerns have been raised that the A6 dual carriageway between Derry and Drumahoe will not open until at least April 2023, it has emerged.
The project, which first began construction in 2016, has been hampered by a number of delays, suffering major setbacks in 2020 due to Covid-19.
The completion of the £185m dual carriageway was due to be completed at the end of this year, but that has now been thrown into further doubt.
