Context

Despite the massively long title, this could simply have been labelled "M12 Motorway", though as the term "Radial Route 7" was still in use at the time, it crops up regularly in the file.

The file is effectively the story of the conception of the M12, and deals with its handing out to consultants for development and design work. There is a lot more here about the administrative aspects of the dealings with private consultants, and of soil surveys, than anything else. It does, however, explain how the M12 came about - essentially after comprehensive improvement of the existing A12 was investigated and found to be extraordinarily expensive, largely owing to the problem of Gants Hill; and the point at which Radial Route 7 became the M12, which was evidently in March 1969.

Comments are here from GLC officers who had clearly been looking at engineering plans of the M12, complete with junction layouts, but the plans to which they refer are (all together now) not here.
