[7] However, by the mid-20th century the industrial development of both sides of the Humber Estuary was becoming increasingly integrated, and "Humberside" was being widely applied to the ports of Hull, Grimsby and Goole and their hinterland.

[8] The use of the term to unify the two sides of the river was also driven by the desire of the local authorities in the area to promote the construction of a suspension bridge.

[9] Unlike "Merseyside", which was used colloquially, "Humberside" was adopted as an official term in 1964, when the planning region of Yorkshire and The Humber was created.

The White Paper that followed the Report did not include a cross-Humber authority either, having named the northern part "East Yorkshire" and kept the southern area in Lincolnshire.

[15] The bridge was finally opened on 24 June 1981, providing a permanent link between North and South, and cutting the journey from Grimsby to Beverley to a mere 30 or so miles, but it did not secure Humberside's future.

The crest was a blue eagle, taken from the arms of the former East Riding County Council, rising phoenix-like from flames, suggesting a new authority emerging from the ashes of the old.

The eagle's wings bore gold droplets standing for North Sea Oil and held in its beak a sword representing the Scunthorpe steel industry.

The blazon (technical description) of the arms is: Per fess Sable and Gules on a Fess wavy Argent between in chief a Coronet Or between two Roses Argent barbed and seeded proper and in base two Fleurs de Lis Or a Bar wavy Azure and for a Crest on a Wreath Or and Gules rising from Flames proper a demi-Eagle Azure Goutté d'Or armed also Gold holding in the beak a Sword point downwards proper hilt and pommel Or.

According to Cran, there was a campaign in 1987 to get Humberside County Council to change its name to something like "East Yorkshire and North Lincolnshire".

This was conducted with an eye to creating unitary authorities, and Humberside was one of the areas that the commission was expecting "early wins" in, and was in the first tranche of reviews.

The Commission recommended that the county and its districts be abolished and replaced with four unitary authorities, a proposal that the government accepted.

[28] There were questions raised as to whether the boundaries of Hull should be expanded, given that they had been set many decades before and never altered despite continuous urbanisation in the neighbouring area, the former urban district of Haltemprice).

Michael Brown, the Conservative MP for Brigg and Cleethorpes, was particularly vociferous in support of the Order, saying in the debate regarding abolition: "I want to see the word 'Humberside' expunged from the English language".

The abolition of the county thus resulted in four successor unitary authorities: There was some debate as to the fate of Goole and the surrounding area, historically part of the West Riding.

Accordingly, local council leaders and members of parliament asked that Postcomm recommend the deletion of North and South Humberside from postal databases.

[35] in August 2013 local MP Graham Stuart brought the issue back to the fore when joint submissions and pleas from other MPs and councillors across the area for the term 'Humberside' to be dropped were made to PostComm.

[36] The campaign was stepped up on 22 November 2013 after MP Graham Stuart stated that the head of the newly privatised Royal Mail had refused to meet him to discuss the matter.

[37] On 2 October 2014 the Royal Mail agreed to remove Humberside from its databases following residents continued protests taken up by Graham Stuart.

Royal Mail's CEO Moya Greene stated "Royal Mail can confirm the technical change required to suppress the automatic reference to North and South Humberside as a Former Postal County on postcode address file products supplied to customers was implemented from July as part of a pilot scheme.

Both the police and the fire service stated that the reason for not pursuing a name change was cost in the present economic environment.
