English: Murdoch's or the Penny Bridge, Carmel Water, Kilmaurs,East Ayrshire. This was the first iron bridge in Ayrshire and was built to provide a shortcut for pedestrians travelling to Knockentiber and Crosshouse as well as a route to the old Woodhill limestone quarries for local workmen and to the old rifle and archery clubs ground on the Carmel Holm next to the Woodhill railway viaduct. It was a wrought iron construction of "fine workmaship" and was paid for by public subscription with every person in the "west" paying a penny towards it. A gala day was held at its official opening. It was still in a good state of preservation in 1895 and was serviceable as late as the 1980s however its significance was overlooked and it was replaced with a wooden bridge at a time when it was around two hundred years old. The Murdoch or Murdock (anglicised version) concerned was William Murdoch (21 August 1754 – 15 November 1839) from Lugar, East Ayrshire, the inventor of gas lighting and an engineer who worked for Boulton and Watt.
