Fact · South Uist
Loch Bì nearly cuts South Uist in two
Loch Bì on South Uist is eight kilometres long and all but cuts the island in half. The main road crosses it on a causeway first built in the 1600s; the current one dates from 1990.
Loch Bì, or Loch Bee, is the largest loch on South Uist and one of the largest in the Outer Hebrides. Dean Monro, writing in the sixteenth century, described the island's 'infinite number of fresh water loches'. Loch Bì is the one that matters: at eight kilometres long it all but cuts South Uist in two. The A865 crosses it on a causeway. The first was built in the seventeenth century; the one you drive over today was completed in 1990.
