In the Faroe Islands, two submerged tunnels that replace the previous two busiest ferry routes caused a sheer improvement of accessibility. Two case communities were studied to see how this affected them. An explorative, mainly qualitative methodology was applied, enriched with supportive quantitative analyses and visualisations. Identified changes include centralisation forces, migration patterns, lifestyle and cultural changes; all of this embodied by increased everyday (auto) mobility. However, a sense of continuity in general and positivity about the tunnel effects prevail. Several mechanisms were identified as to why the overall impact is perceived so limited – including a cultural ‘tunnel vision’ trait that is reflected in infrastructure planning. The methodology was found adequate in answering the research questions. %D 2017 %A R. Hokwerda %T Tunnel Visionary: The societal effects and impacts of sub-sea tunnels on the Faroe Islands
