Nice viaduct @Skyla! Where is this?
Harringworth, I’d reckon?
Yes Harringworth but i done a flight plan the day before, as there is a small airfield close by.
The longest viaduct on the UK. 
Nope - the Tay Bridge is the longest railway viaduct, and Bromford Viaduct the longest road viaduct. Both are far longer than this one.
The Tay Bridge is a … bridge. 
OK - if we’re getting picky - the one at Harringworth is the longest masonry viaduct in the UK.
So the longest “proper” viaduct.
Modern stuff gets ignored. 
Now I’ll have to go googling again … 
Several of the railway viaducts in London are probably longer e.g. Kingsland Viaduct in Hackney …
A fine photo and finer bit of Victorian engineering.
Thank you for the kind reply.
looks a good one! Nice picture!
