The proposals for the inner ring are really astounding - it would have gone right through all sorts of lovely historical neighbourhoods, across nice local parks - right through many of the nicest inner suburbs in London. Every time I see the fortress-like sides of Southwyck House in Brixton I'm reminded of it. If it had gone ahead it really would be a completely different city today.
Today Oslo has major roads in tunnels under parts of the city. My impression visiting was that this is how you would solve the problem if you had infinite budget.
