Sure, it all goes to plan for a few years. Then ever more people start to use
the route and in a decade or so you're back where you started except now the
jams have twice as many cars with twice the pollution. The best example of
this
in the UK is the M25. No matter how much they widen it it just jams up again
in a few years. It has 6 lanes each way around Heathrow yet they're still
often
jammed solid in the rush hour. So what do you do, widen it to 8 lanes, 10?
Where does it stop?
When they plan it better and segregate the long distance and local
traffic. The problem with that bit of the M25 (and I lived *there* 25yrs
ago and saw it first hand) was mixing them up.
And how do you plan to segregate them? Either you allow local traffic onto
the M25 or you close the junctions.
The newest bit of A14 (remember, the road we are discussing) segregates
them, just as the A1(M) north of Huntingdon does, the road which hasn't
shown any sign of jamming up 20yrs later.
I doubt many people use the A1 for long distance travel in the south or midlands
as there are too many roundabouts, too much slowing down and speeding up and
too many selfish truckers doing the tortoise race holding up a quarter mile of
traffic as they pass each other at 0.5mph difference in order to gain 1 minute
that they immediately lose at the next roundabout anyway.
