In addition to the major North Ford () and South Ford causeways that connect North Uist to Benbecula via the northern of the Grimsays, and another causeway from Benbecula to South Uist, several other islands are linked by smaller causeways or bridges. Great Bernera and Scalpay have bridge connections to Lewis and Harris respectively, with causeways linking Baleshare and Berneray to North Uist; Eriskay to South Uist; , and the southern Grimsay to Benbecula; and Vatersay to Barra. This means that all the inhabited islands are now connected to at least one other island by a land transport route.
