The Overtoun Bridge is an arch bridge located near Milton, Dumbarton, Scotland, over the Overtoun Burn. It has gained public attention because of the unusually large number of dogs that have allegedly leaped to their deaths over a number of decades.
The Overtoun Estate is located on a hill overlooking the River Clyde, above the village of Milton and the town of Dumbarton. In 1859, James White, a rich man, bought over the surrounding areas with the purpose of building a mansion there. He intended for it to be a retreat from the busy city streets, and initially acquired 900 acres ; he soon increased this to 2,000 acres. White hired the well known architect, James Smith (Architect 1808 -1863) (father of the infamous Madeleine Smith), to design and construct the house. A farmhouse previously on the site was demolished to build the mansion. Smith died before his work at the Overtoun mansion was completed. The house, built on stone, was completed by one of his work partners. White’s family began living in the mansion in 1862.
