- EXECUTIVE SUMMARY
This Strategic Outline Business Case sets out the rationale for a fixed crossing of Strangford Lough to replace the current ferry service between Portaferry and Strangford. With a target completion date of 2030, the project would deliver critical connectivity infrastructure supporting economic growth, social inclusion and decarbonization objectives.
The analysis concludes a fixed crossing offers the optimal long-term solution compared to maintaining reliance on ferry services, with benefits significantly outweighing costs over the infrastructure lifecycle. The proposal aligns with strategic infrastructure priorities and can be delivered within established major project frameworks.
Project Overview:
- Fixed crossing connecting Portaferry and Strangford (c.0.6 nautical miles)
- Estimated capital cost: £300-350m
- Construction period: 2027-2030
- Operational date: Late 2030
Recommendation: Proceed to Outline Business Case stage and begin detailed feasibility work in early 2025.
