Dunglass Viaduct

The Dunglass Viaduct is an important six-span railway bridge which carries the East Coast Main Line across Dunglass Dean and the Dunglass Burn on the boundary between East Lothian and the Scottish Borders, ¾ mile (1.2 km) northwest of Cockburnspath. The bridge opened in 1846, the work of John Miller (1805-83) for the North British Railway, which was the first railway connecting Scotland and England.

Constructed in masonry, with ashlar buttresses, it is 86.9m / 285 feet in length, with its main span of 41.1m / 135 feet representing one of the largest masonry arches in Scotland reaching 33.5m / 110 feet above the Dunglass Burn.

The structure was B-listed in 1971 and gantries added during the 1980s to carry the overhead wiring for electrically-powered trains.
