Rusty bridge?

This is the new Sighthill Cycle and Footbridge over the M8 motorway. It's made of Corten steel so looks rusty. It connects the north of the city with the totally regenerated area of Sighthill where all the tower blocks have been demolished and new more modest height homes are being constructed. 
It was a beautiful day too. Just look at that sky!
Sighthill was where Douglas Stuart (author of Shuggie Bain and Young Mungo) lived as a boy. He wouldn't recognise it now.
