The bridge crosses the Humber Estuary between Hessle, East Yorkshire and Barton upon Humber, North Lincolnshire.
The bridge was the world’s longest single-span suspension bridge when it opened and held this record for 16 years.
It is the UK’s longest single-span suspension bridge and now the eighth longest in the world.
It remains the longest in the world that can be crossed on foot or by cycle.
The bridge is made up of three spans; Hessle side span (280 metres), Barton side span (530 metres) and the main centre span (1410 metres) making a total of 2,200 metres or 1.4 miles.
The road deck, which is made up of 124 steel box sections weighing over 17,000 tonnes is designed as an upside-down aircraft wing, to help keep the deck stable during high winds.
The concrete towers are 155.5 metres (510 feet) tall and were built to be 36mm further apart from each other at the top than at the bottom, to allow for the curvature of the Earth.
There is enough wire used in the bridge to go around the Moon more than six times.
The bridge is open 24 hours a day, seven days a week, 365 days a year.
In February 2002, the 100 millionth vehicle crossed the bridge as part of the 6 million crossings that year. The bridge is now carrying more than 10 million vehicles every year.
