Whalley Railway Viaduct

Aqueduct yesterday - Viaduct today - what kind of -duct can I blip tomorrow?
Went to Whalley & Clitheroe today and whilst Mrs MD was looking for 'Mother of the Bride' outfits - I scooted off with Polly dog to have a walk in the sunshine down by Whalley Abbey.
We came across this rather magnificent railway viaduct - and this blip is only of one half of it!
My 'research' informs me the Whalley Viaduct was built to carry the railway over the river Calder. It is the longest brick viaduct in Lancashire. 605 m long, consisting of 29 arches of 9 m (30ft) and 20 arches of 12 m (40ft). Building started in 1850 and it took three years to complete at a cost of £40,000. The arches are 21 m (70ft) above the River Calder and 7,000,000 bricks were used.
Wow :-)
