Leaderfoot Viaduct, also known as the Drygrange Viaduct, is a striking Victorian railway structure spanning the River Tweed near Melrose in the Scottish Borders.

Designed by engineers Charles Jopp and Wylie & Peddie, it was opened in 1863 to carry the Berwickshire Railway, rising 126 feet above the river valley on 19 tall, slender red sandstone arches.

The line closed to passenger traffic in 1948, and the viaduct is now a Category A listed structure.

The site sits within the National Scenic Area of Eildon and Leaderfoot, where the Leader Water meets the River Tweed — a location with deep historical layers, including a nearby Roman crossing that once served the fort at Trimontium.

Three bridges now cross the river at this point, making it a remarkable spot for anyone interested in engineering or history.

Visitors can view the viaduct from the road or on foot by crossing the adjacent Drygrange Bridge, a pedestrian and cycle route dating from 1780. Parking is available at the nearby Old Melrose Tearoom.
