Fascinating Facts about the Humber Bridge
The bridge crosses the Humber Estuary between Hessle in East Yorkshire and Barton upon Humber, North Lincolnshire.
Construction started in July 1972 – the bridge was officially opened by the Queen on 17th July 1982.
The bridge is open 24 hours a day, seven days a week, 365 days a year. Both towers are 155.5 metres (510 feet) tall.
The bridge is 1.4 miles long.
The total length of the suspension cable is 43,000 miles. That’s nearly twice the circumference of the Earth (24,901 miles).
The centre span is 1,410 metres (4,626 feet), with the bridge’s total length coming in at 2,220 metres (7,283 feet).
The towers are 36mm further apart from each other at the top than at the bottom, this is to allow for the curvature of the Earth.
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. In 2017 the Humber Bridge was given Grade 1 listed status by Historic England, making it the longest listed structure in the UK.
Latest figures show there are more than 10 million crossings every year.
The Humber Bridge now operates the first hybrid tolling system with automatic payments, through the HumberTAG scheme, which went live in November 2015.
In September 2016, the Bridge Board announced a toll freeze for five years. The Humber Bridge Board, which operates the bridge, is a statutory highway and traffic authority.
The road deck is made up of 124 steel box sections, each one weighing 140 tonnes. The road deck is actually designed as an upside-down aircraft wing—to help keep the deck stable during high winds. This also means that, unlike many other suspension bridges, it has inclined hangers connecting the deck to the main cable as against vertical.
