CNRR (N40 North)
4.143 The N40 Demand Management Study, which was published in 2017, recognised that future traffic demand on the N40 will need to be managed if this road and the Jack Lynch Tunnel are not to act as a constraint on development within the Cork Metropolitan Area. 4.144 The TII Demand Management Study identified a number of proposals under the following broad headings. • Integrated Land use and Transportation • Targeted Upgrades; • Smart Motorway Interventions; • Alternative Complementary Routes; and • Fiscal Measures. 4.145 Measures such as those outlined above can have a positive impact on managing future demand on the N40, notwithstanding the complexity of the overall road network in the CMA and the limited alternatives to the Jack Lynch Tunnel. Cork City Council will support rollout of public transport, land use policy and traffic management measures in the short-medium term. Measures will not be introduced in isolation but only after due consideration of the impacts on access and movement across the City and suburbs and in parallel with the introduction of necessary appropriate alternatives to service affected traffic movements. The upgrade of the N40 South Ring Road to motorway status is one of the key recommendations of the study, primarily to limit its use to motorised vehicles and to remove the small number of cyclists, pedestrians and slow moving vehicles in the interests of road safety.
4.137 The Cork North Ring Road/N40 north (CNRR) linking the N20 to the Dunkettle Interchange is currently being appraised. 4.138 The CNRR is a complementary but independent scheme to the N/M20 corridor scheme. It is envisaged that the CNRR would not be delivered in advance of the substantive public transport elements of the Cork Metropolitan Area Transport Strategy (CMATs). 4.139 Application of appropriate safeguards within the study corridors and the application of appropriate development densities to ensure the long-term feasibility of the proposed routed by Cork City Council will be applied in this Development Plan should they emerge during the lifetime of this plan. When an emerging preferred route is identified a variation of this plan will take place to safeguard the route.
N40 Demand Management
4.140 The N40 Cork South Ring Road is the most heavily trafficked roads in the Southern Region and forms part of the Trans-European Transport Network (TEN-T). 4.141 The N40 corridor was constructed and upgraded incrementally since the early 1990s between Junction 1 (Poulavone) and Junction 11 (Dunkettle) over a number of decades at significant investment. 4.142 In more recent years, infrastructural work along the N40 has tended to focus on maximising the efficiency and throughput of the corridor with a number of interchange grade separation schemes completed The Dunkettle Interchange (Junction 11) represents the last at-grade junction on the N40 and is currently being upgraded to a free-flow junction.
4.146 Cork City Council will support Transport
Infrastructure Ireland (TII) to undertake traffic management and improvement studies focussed on the N40 to assess current capacity constraints and to identify potential future improvements to the operational safety of this key strategic route.
