Regent Bridge in Edinburgh, Scotland, is a cool arch bridge that was built back in the 19th century. It's where the A1 road enters the New Town from the east and passes over a hollow near Calton Hill. The bridge was constructed to make the city more accessible and elegant, replacing old streets with a fancy arch called Regent Bridge. It's a neat example of Greek Revival architecture and was officially opened in 1819 during Prince Leopold of Saxe Coburg's visit to Edinburgh.
