Local authority boundary changes brought the town into the new county of Humberside in 1974, and a new non-metropolitan district, the Borough of Scunthorpe was formed with the same boundaries as the old municipal borough. The opening of the Humber Bridge on 24 June 1981 provided a permanent link between North and South Humberside but did not secure Humberside's future. To the relief of its many detractors, the county of Humberside (and Humberside County Council) was abolished on 1 April 1996 and succeeded by four unitary authorities.
