The Humber Bridge opens to traffic, connecting Yorkshire and Lincolnshire. It would be the world's longest bridge span for 17 years.

The Humber Bridge, near Kingston upon Hull, East Riding of Yorkshire, England, is a 2.22 km (2,430 yd; 7,300 ft; 1.38 mi) single-span road suspension bridge, which opened to traffic on 24 June 1981. When it opened, the bridge was the longest of its type in the world; it was not surpassed until 1998, with the completion of the Akashi Kaikyō Bridge, and is now the twelfth-longest.

The bridge spans the Humber (an estuary formed by the rivers Trent and Ouse), between Barton-upon-Humber on the south bank and Hessle on the north bank, connecting the East Riding of Yorkshire with North Lincolnshire. Both sides of the bridge were in the non-metropolitan county of Humberside until its dissolution in 1996. The bridge can be seen for miles around and from as far as Patrington in the East Riding of Yorkshire and out to sea miles off the coast. It is a Grade I listed building.

By 2006, the bridge carried an average of 120,000 vehicles per week. The toll was £3.00 each way for cars (higher for commercial vehicles), which made it the most expensive toll crossing in the United Kingdom. In April 2012, the toll was halved to £1.50 each way after the UK government deferred £150 million from the bridge's outstanding debt.
