The Tay Bridge carries rail traffic across the Firth of Tay in Scotland between Dundee and the suburb of Wormit in Fife. Its span is 2.75 miles. It is the second bridge to occupy the site.

Dundee is the fourth-largest city in Scotland. The mid-year population estimate for 2016 was 148,210, giving Dundee a population density of 2,478/km2 or 6,420/sq mi, the second-highest in Scotland. It lies within the eastern central Lowlands on the north bank of the Firth of Tay, which feeds into the North Sea. Under the name of Dundee City, it forms one of the 32 council areas used for local government in Scotland. Within the boundaries of the historic county of Angus, the city developed into a burgh in the late 12th century and established itself as an important east coast trading port. Rapid expansion was brought on by the Industrial Revolution, particularly in the 19th century when Dundee was the centre of the global jute industry. This, along with its other major industries, gave Dundee its epithet as the city of "jute, jam and journalism".
