The Seilebost Causeway crosses one of the inlets at the head of Traigh Losgaintir, as the A859 returns to the West Coast of Harris. It replaced a lengthy loop through the rocky hills around the salt marsh, and so cut over half a mile off the journey.
The causeway itself is roughly 500m long, and crosses the tidal creek, which is the outflow from Loch Carran and Abhainn Gil an Tailleir, with a small bridge before proceeding across the beach and salt marsh. Simply constructed of rock dumped on the ground, with a single track road laid over the top.
