From the Sound of Harris Ferry
The Causeway from North Uist to Berneray is approximately 900m long and two-way for its entire length. It crosses to the west of the former ferry slips and was opened by Prince Charles in 1999 after being completed late the previous year. There are no bridges, as Berneray is only a small island, but a number of culverts were provided for fish and marine mammals to use. Over 300,000 cubic metres of rock was used to construct the causeway, mostly from a local quarry.
History - The Ferry
Before the Causeway was built, the crossing to Berneray was made by a lifeline pedestrian ferry running between the slips to the east of the causeway. Some crossings also went to Leverburgh, although still as a pedestrian only service. Just three years before the completion of the Causeway, a vehicle ferry service started operation from the slipway on North Uist, crossing to Leverburgh / An t-Ob on Harris. However, once construction was completed, the service transferred to the slipway on Berneray which is slightly easier for the ferry to access.
