Thames Tunnel publication

Subfond DG/PUB/01 is made up of bundles of leaflets, seemingly grouped together at random. This one is listed under the title "Thames Tunnel Publication" and in it you'll find a leaflet describing the GLC's plans for a tunnel to carry Ringway 2 under the Thames at Gallions Reach. This much we knew, and there's little technical detail here, with it being a basic leaflet to be sent out to the public when the scheme was announced. This leaflet does have a neat diagram of the plan, though, including a plan of the proposed layout of Ringway 2's interchange with the Thamesmead Spine Road.
What's really nice, though, is that among the other publications in this file is a document titled A23/M23 Route Study, which appears to be a late 1970s or early 1980s report investigating ways in which the M23 could be completed without Ringway 2 in place. It investigates various options, but the general proposal seems to be a motorway or dual carriageway in as far as Mitcham Common, where it would terminate at a roundabout, from which two new single-carriageway roads would disperse traffic. One would go east to reach the A23; the line of this road matches the access road now known as Ampere Way that runs from the B272, past Ikea and on to the grade-separated junction on the A23 Purley Way. The other would have gone north west to a new junction with existing roads somewhere around Mitcham Junction.
This is a new document that I haven't seen before and it doesn't seem to appear in the LMA's catalogue listing, so it was quite an exciting file!
