The planning, design and implementation of national road improvement projects is a matter for the National Roads Authority and the local authorities concerned. The provision of rail services is a matter for Iarnród Éireann to consider. The strategic rail review, however, foresaw no requirement for railway infrastructure north of Sligo. I understand from the NRA that the proposed road upgrade project from Sligo to Donegal county boundary is at route selection stage and public consultation to present the route options was held at various locations affected by the proposed routes in October 2004.
While the scheme is at an early stage of development, it is envisaged that the project will be constructed mainly as a 2+1 roadway. This roadway type consists of two lanes in one direction of travel and one lane in the opposite direction. The two lane section, which provides a safe overtaking zone, is alternated with a one-lane section at intervals of 2 km approximately. The traffic streams are separated by a safety barrier system which prevents overtaking manoeuvres on the one lane section. Right turning movements are catered for at controlled junctions along the route. I understand, it would neither be feasible nor practicable to incorporate a rail corridor running in the central margin or on either side of the proposed scheme.
