The Baleshare Causeway crosses the tidal channel between North Uist and Baleshare, just off the larger islands south west coast. It was opened in 1962, as the last connection in the Uist Chain to be built by Inverness-shire County Council. All subsequent works have been built by Comhairle nan Eilean Siar.
The causeway is 350m long, and entirely single track with two intermediate passing-places, both on the north side. There are no bridges along its length, which has resulted in the sands building up on the northern flank, whilst the tide can be in on the south side!
Before the causeway was built, there was no reliable service connecting Baleshare to the outside world, each family would probably have owned their own boat, with some being hired out to visitors. At Low tide the channel could be crossed on foot without too much difficulty.
