Motorway on Stilts

This is the Rakewood Viaduct, Littleborough carrying the M62 over Rakewood Valley between Junctions 21 and 22.
You could be forgiven for not recognising it, most people drive over it without a thought.
It is 840 feet long, 140 feet high and was built in 1966.  It opened to Motorway traffic in 1971.
In extras I have put a photograph from the Archives of the viaduct being built.
