	The M1-A1 link road was constructed between 1989 and 1991 following a lengthy period of consultation. The first inquiry was in 1974 and then a series of inquiries for sections of the preferred route from September 1984 until June 1985, during which objections came from some 1,130 sources. Subsequent public inquiries were held regarding Supplementary Orders. The route close to the site of the Battle of Naseby was particularly difficult and was taken to the High Court. The link was opened by John MacGregor, Transport Secretary on 15 July 1994.
