Publication Account (2007)
An imposing masonry structure designed by Robert Stevenson & Sons for Mr Balfour of Balsillie and now carrying the B6437 road over the Whitadder Water. It was built from 1840–42 and has two segmental spans each of 75 ft with a low rise of 1112 ft. The resident engineer was J. T. Syme.The elevation, with its rectangular pilasters, imparts boldness to the bridge’s appearance and offsets the duality of the twin spans. The masonry is of broached ashlar, except for the pilasters, frieze, cornice, impost courses, and the base and coping of the parapet. The stone is generally local soft red sandstone except that for the springing courses which was from Daleky (Dalachy) Quarry, Fife. The arch stones are 3 ft deep at the haunches and 2 ft 6 in. at the crown with their joints radiating across the spandrel facing.
