The A42 was built by the UK Government in 1989 to link the northern section of the M42 to the M1. Although it is not designated as motorway, and has no hard shoulder, the road is fully grade separated and runs with two lanes each way, the same as the M42 to the south.
The original planned line of the M42 saw it joining the M1 further to the north, crossing what is now the A50 Derby Southern Bypass and meeting the M1 north of Bardills Island (A52/M1 interchange)[citation needed]
The current road is the second incarnation of the A42. The original (1923) route was Reading to Birmingham via Oxford. The whole road was renumbered in 1935 – the section from Reading to Shillingford became part of the A329, Shillingford to Oxford became part of the A423 and Oxford to Birmingham became part of the A34. In 1993 the A423 was itself renumbered, with the section formerly the A42 becoming part of the A4074 from Reading to Oxford. The modern M42 does interchange with the former A42 at junction 4 near Solihull: Stratford Road now being numbered A34 to the north of the junction and A3400 to the south.
