Work is to begin next week (Monday 18 January) on construction of a new lit beacon in the Sound of Harris.
Northern Lighthouse Board has issued a Notice to Mariners ahead of the work, which will be adjacent to the existing Portain buoy station.
A barge is to be positioned in the Sound as the initial phase of building a submerged concrete foundation begins. The foundation will then be marked with temporary marker buoys.
A further notice is to be issued ahead of the establishment of the lit beacon and the removal of the starboard hand buoy.
