The following factors were taken into consideration:
- providing a strategic link from the A6 dualling scheme at Drumahoe to the A5 dualling scheme at Newbuildings;
- extending this strategic A5/A6 link across the Foyle to Donegal, however, the benefits of the latter could only be realised if there was an appropriate high quality link to the National Roads Authority strategic road network; and
- providing a local distributor ‘West Link’ connecting from the strategic A5/A6 link and skirting around the west of the city to Buncrana Road. This would be challenging and would require a much more detailed investigation to examine its buildability and the benefits arising.
