Slater’s Bridge is a 17th century packhorse bridge in Little Langdale in the Lake District in northwestern England. The bridge crosses the River Brathay and is built of slate. It consists of a 15-foot segmental arch and a flatter span built of slabs and incorporates a natural boulder in midstream. The bridge is thought to have been created by miners working in the nearby Tilberthwaite slate quarry to shorten their walk between the quarry and their homes.
