Some traffic problems exist already, yes. However, isn't it obvious that a
high-quality "outer M25" route will generate lots of extra traffic above
and beyond the traffic that currently exists?

It will create extra traffic but it will also reduce the use of some
neighbouring roads. If the A421 were dual all the way from the A1 to the M1
I (and a lot of others) wouldn't drive through Kempton and use the A422,
which has to be a good thing.

Saying that I don't think the plans for the A14 are worthwhile and the Great
Barford bypass on the A421 is only worthwhile because it will take traffic
from the village
