Ribblehead Viaduct by Tom Blackwell

The Ribblehead Viaduct is an epic stone structure which is some 24 arches long and soars over a hundred feet tall. Built in 1875, it is the longest and most famous viaduct on the Settle-Carlisle Railway, an old Victorian line which passes through a magnificent range of northern scenery as it wends its way through the Yorkshire Dales into Cumbria. The structure happens to rest on the ancient boundary between the North and West Ridings of Yorkshire, marking a long-forgotten dividing line along the Pennine mountain foothills.

Panorama photography is one way of trying to convey the breadth of this impressive engineering work - it is truly vast in size! This image is a composite which has been stitched together from six seperate shots taken close to the viaduct on its western face.
