The Nant Ffrancon Pass in Snowdonia, North Wales is at 312 metres (1,024 ft) at Pont Wern-gof, about one-third of a mile beyond the eastern end of Llyn Ogwen. Nant Ffrancon itself is a steep-sided glacial valley dropping to Bethesda between the Glyderau and the Carneddau. The A5 road crosses the Nant Ffrancon Pass between Llyn Ogwen and Bethesda, Gwynedd. The original road through the Nant Ffrancon was constructed by Lord Penrhyn in the late 18th century. Lord Penrhyn’s road, largely followed the valley floor. Thomas Telford re-engineered it between 1810 and 1826. Telford carved much of his road out of the north-eastern slopes of the Nant Ffrancon, thereby encountering difficulties in construction and future maintenance. But this enabled him to observe a maximum grade of 1 in 14 along the whole route from London to Holyhead in order to facilitate horse drawn mail coaches throughout.
