Tay Bridge
The second bridge opened on 13 July 1887 and is still in use. In 2003, a £20.85 million strengthening and refurbishment project (£ as of ), on the bridge was completed. More than  of bird droppings were scraped off the ironwork lattice of the bridge using hand tools, and bagged into  sacks. Hundreds of thousands of rivets were removed and replaced. All work was done in very exposed conditions high over fast-running tides in the river.
