Ballochmyle Viaduct was one of the greatest engineering achievement of it's time. The Engineers, Grainger and Miller from Edinburgh knew they had a task on there hands but decided to take on the job of building the then worlds largest masonary span arch. Work started on March 1846 and the first foundation stone was laid on 5th September 1846.

The arch rings, of which the main arch span is 55.6 metres and 51.5 metres high, were made from stone brought in from Dundee by rail and the last stone was laid on 12th March 1848. The woodlands site surrounding the bridge is dominated by Mature Oak, Sycamore, Hazel, Birch, Beech, Ash, Scots Pine, Norway Spruce and Elm trees. The bridge boasted stardom in the film Mission Imposible when the famous scene on the top of the train was filmed while the train crossed over the viaduct with the town of Catrine clearly visible in the background.

The Cup and Ring markings can be found near the bridge and consist of over 200 markings some of which are unique to the area. The carvings have been dated between the Neolithic and early Bronze age and reckoned to have been made over a period of about 1000 years. The marking would have eroded long ago if they had not been made on this unusual face of "hard sandstone"". The Markings lay unnoticed until 1986 when a local man walking his dog spotted them. The site is among the top 10 most important "Cup and Ring" sites in Britain.
