APERTURE CARDS OF TRUNK ROADS SCHEMES

Some years ago, I wrote:
- "A file of road scheme plans stored on aperture card, which are in no particular order and seem to contain random extracts from much larger files. It is rather infuriating to find one fragment of a really interesting scheme, with no further information available on it."
There seems to have been some effort to organise this box of cards now, because someone has clearly gone through all the drawing numbers marked on the cards and grouped them by scheme, numbered each group, and indexed them. Hoorah for that.
Unfortunately, in the same timeframe they have scrapped a load of old equipment, meaning it's no longer possible to see the contents of the aperture cards on the viewer and it's no longer possible to get paper copies or enlargements of them either.
Among the many bundles of new bus lay-bys and signal timing diagrams are to be found the following gems.
- Proposals drawn up in 1980 by the GLC to provide a new left-in-left-out junction on the M41 to allow access to a development side on the east side of the motorway at Freston Road. Three options are presented which are almost identical, and the scheme never happened.
- Alternative proposals for the A41/A406 Brent Cross Flyover, including one that appears to be a full cloverleaf almost entirely within the footprint of the existing junction, if you can imagine such a thing.
- The "Whitehall Traffic Scheme" - a real jackpot find that I may return to if the LMA ever regain the ability to produce copies of these cards. It seems a firm of consultants was asked to come up with ways of alleviating the traffic problems at Parliament Square, and came up with no less than 26 options, lettered A-Z, all of which are wild flights of fancy involving roads under the Thames past Parliament and underground interchanges on the Embankment. My favourite was the one that shows a free-flowing interchange built entirely in tunnel below the Treasury. The 26 route options are on cards 4989 to 5025.
- A scheme for a flyover or underpass at Golders Green Road, which is the set of traffic lights on the A406 North Circular immediately east of the A41 Brent Cross Flyover. There are about four different proposals here, circa 1979.
In 2005 I saw the same box and also found these things, though at the time there were no reference numbers for them so the best I can say is that they are somewhere in the box.
- Plan showing "North and East London Major Road Network", produced by the GLC in February 1966. It shows the Lea Valley Route for the M11 and the PNLR, with junction locations.
- Plan of section of the M11 scheme from the railway yards north of Stratford to the Leytonstone tunnel. The plans either side of this, which would have shown the layout at Green Man and Hackney Wick, are not present here. It was produced by WS Atkins for the Ministry of Transport.
- Sheet of predicted motorway flows for 1981, produced in March 1968 by WS Atkins on behalf of the GLC, with schematic junction layouts from Hackney Wick to Green Man.
- Three alternative route options for the M11 between Hackney Wick and Redbridge, drawn up for the Ministry of Transport by WS Atkins, and undated.
- Proposed signage scheme for urban motorways, drawn up by the GLC's Highways and Transportation department in September 1965. These differ significantly from motorway signage in TSRGD at the time.
