Irish Sea Bridge, Proposed bridge across the Irish Sea between Scotland and Northern Ireland, United Kingdom.
The Irish Sea Bridge is a proposed structure to cross the Irish Sea between Scotland and Northern Ireland. The project includes two potential routes: a longer span from Portpatrick to Larne covering roughly 45 kilometers or a shorter option from Kintyre to Ulster spanning roughly 20 kilometers.
The idea of linking Great Britain and Ireland through a fixed crossing dates back to Victorian times. Interest in this project revived from 2018 onwards and has since sparked political and technical discussions.
The bridge project represents an effort to strengthen connections between communities in Scotland and Northern Ireland through direct transportation infrastructure.
The route must span extremely deep water channels reaching depths of 270 meters, making construction highly complex. Additionally, the presence of World War II munitions in Beaufort's Dyke significantly complicates technical planning.
The estimated cost of roughly 335 billion pounds would make this the most expensive transportation project in British history. Such an investment would be unprecedented compared to other major infrastructure projects in the country.
