About 6 years ago I remember that a road called the "Bexley Bypass" was marked with dotted lines on a street atlas. On all of the recent ones (of the same and other make) no longer show this.
It was proposed to go from the A2 somewhere between Bean and Bexleyheath, to the North Cray Road, and Maybe the A20.
The Google Satalite image below shows the roundabout where it joined on the map (It currently serves no purpose, and I don't think that the access road to the left exists anymore.
There are quite a few houses between the A2, and a few would need to be smashed away for the bypass, unless it was proposed to be built over them like a flyover.
But that is a very small and un-important reason for this major road to be left un-built. At the present time, traffic has to use the very small village of Bexley to access the A20, and towns around it, or use the M25, which is also very busy and some are BANNED from using the M25 (IE. L Drivers, Horse & Pony riders, slow moving tractors.ect).
Is there any information about this proposal?, and what are your views on it?
