Shetland Islands Council Approves Feasibility Study for Undersea Tunnel Network
7/1/2026, 12:55:41 AM
Proposed Undersea Tunnel Network
On 30 June 2026 Shetland Islands Council approved a feasibility study for subsea tunnels linking the Mainland with Yell and Yell with Unst. Construction of the two tunnels is estimated at £652 million; a four-tunnel system, adding Whalsay and Bressay, would cost about £1.5 billion and could be finished within eight years.
Transport Challenges and Decline
Shetland’s ferries average 32 years, suffer staffing shortages, limited capacity and frequent weather cancellations. The 12-vessel fleet carries roughly 750 000 passengers yearly at a £23 million operating cost. The population has declined 24 percent over four decades, a trend linked to transport insecurity.
Proponents and Local Views
Council leader Emma Macdonald and chief executive Maggie Sandison back the tunnels. Tavish Scott of Salmon Scotland and Brydon Barclay of Fluggaboats also support them. Spokesperson Alice Mathewson stresses the links’ potential to boost prosperity and wellbeing.
Cost, Ferry Usage, and Economic Data
The two tunnels cost £652 million; a four-tunnel network is projected at £1.5 billion. Ferry operations cost £23 million. Shetland provides 22 % of Scotland’s farmed salmon, 88 % of its mussels, and seafood landings worth £147 million.
Impact on Economy, Demography, and Environment
Fixed links are expected to reverse depopulation, attract investment and cut carbon emissions by reducing ferry trips. Reliable transport would also strengthen the salmon-farming supply chain and support other sectors.
Official Statements & Responses
The council said “both ferries and tunnels are needed to unlock the potential of Shetland” and will seek funding from the Scottish National Investment Bank, the UK national wealth fund and private investors. The Scottish Government confirmed a £13 million grant for the feasibility study and pledged cooperation under its national islands plan. Funding options include tolls, public subsidies, borrowing and private-sector participation.
Criticism & Opposition
Orkney Islands Council warned that tunnel solutions may be less relevant for other archipelagos, citing existing fixed links such as the Churchill barriers. Some observers flag the £1.5 billion price tag and reliance on tolls and private capital as financial risks.
Conflicting Reports & Gaps
Sources agree on construction costs but differ on the financing mix; no final agreement exists on the share of public subsidy versus private investment. Detailed implementation schedules beyond the eight-year horizon remain pending.
