Further improvements in the late 1960s and 1970s saw construction of the £5.2 million (£ in ) Mickleover bypass to the south-west of Derby opened on 19 February 1975. Although the government had approved the section through Allestree as early as 1974, before the Mickleover bypass had been completed, this section had many objections from nearby residents, delaying its construction (from the A52 to the A6). It was opposed directly by Derby Borough Council and the former Derby Higher Education College. The £17 million (£ in ) road was eventually opened on 7 September 1983, known as "Queensway". An extension of the A38 northwards, crossing the M1 at Junction 28, and ending in Mansfield was built. The £3 million (£ in ) Little Eaton-Holbrook Improvement opened on 3 October 1977.
