"BRIDGEND, a hamlet in the parish of Melrose, Roxburghshire. It stands about a mile west of the town of Melrose, adjacent to the bridge of the Edinburgh and Jedburgh highway. An ancient bridge of curious construction stood here, said to have been built by David I. to facilitate communication with Melrose abbey. It had a central tower, containing the keeper's residence."
