Here's a thought (suggested by an SE1 ringer). Many apologies if it's come up before - I haven't seen it.
What's the point of the flyover which goes over the Bricklayers Arms Roundabout? It only goes in one direction and as far as I can see any congestion it takes away from the roundabout goes straight back into congestion on Old Kent Rd. In practice is it any use? (I live nearby but I've virtually never used it as there are better ways to access roads in both directions).
How about closing it to traffic and transforming it into an elevated park - could be something really special?
One aspect not mentioned here is the speed of traffic going south on NKR. It's pretty bad anyway - often in both direction but seems to accelerate markedly on approaching the flyover - I think this makes people feel they're on the way out of the city onto major roads - they then arrive at OKR with shops, more traffic lights and asmuch if not more pedestrian activity.
I suspect the flyover encourages speeding on NKR.
Doesn't the flyover in fact go above what used to be Parragon Park at the top end of Darwin Street (formerly Pitt Street)? Does anyone have knowledge/folk history of when the park went - I imagine after the 39-45 War and local bombing?
The Paragon Crescent existed on the South side of New Kent Road and was swept away by the widening of New Kent Road which was part of this project.
The whole area was cleared from 1968 onwards to make space for the road junction, but despite heavy bombing nearby, this wholescale demolition was not as a result of WWII, but was planned as part of an inner ring-road or motorway box. The NW section of this project was built however, and is called the Westway.
Local political opposition in London and the oil crisis scuppered the scheme in the early seventies. I also suspect that the money ran out as the country entered a serious recession and political crisis.
A terrace of victorian buildings on the North side Old Kent Road survives almost as far as the roundabout - this gives you an idea of what the original street layout was like. At the centre of the roundabout you can still see the old LCC tramway manhole covers in exactly the same location as they were before the municipal vandalism began.
