Beaufort's Dyke

Description

This is a marine trench between Scotland and Ireland. It is a notable barrier to the building of a fixed link between the countries. In addition to the depth of the trench, there was dumping of considerable quantities of surplus munitions for over ten years following the Second World War. Further, nuclear material was dumped here in the 1950s.

Several schemes have promoted tunnels between the countries. In 1901 this was chosen as a suitable route for a railway tunnel, the tunnel would run from Portpatrick to Whitehead and pass round the north end of the underwater feature. The idea was revived in 1934. Such a tunnel would have linked the Portpatrick Railway with the Carrickfergus and Larne Railway.

Again, in 2020, a fixed link bridge or tunnel was proposed.

Chronology Dates

  /  /1901International Engineering Congress, Glasgow
Three tunnel routes considered from Scotland/Wales to Ireland: Mull of Kintyre to Antrim (revival of the 1868 proposal, rejected due to remoteness of Kintyre), Holyhead to Howth (rejected due to length), Wigtownshire to Larne/Donaghadee (passing north round the deep trench of the Beaufort's Dyke). Latter considered most suitable with a route from north of Portpatrick to Whitehead.
  /  /1945Cairnryan Military Railway
Surplus munitions start to be dumped in the Beaufort's Dyke, much conveyed by rail to Cairnryan.
  /  /1958Cairnryan Military Railway
Dumping of munitions in the Beaufort's Dyke ceases.
