The 72 mile Settle-Carlisle railway line was built by the Midland Railway in 1869-76 to give it an independent route to Scotland north of Ingleton. It was probably the most heavily engineered line built England and the expense, financially and in human cost was huge. Apart from the great Ribblehead Viaduct there are many others. The highest of these structures and among the largest is Dent Head, an attractive 10 arch viaduct crossing the head of Dentdale about 10 miles north east of Ingleton.
