It is and it isn't, it will keep a lot of people employed, and a lot of families out of trouble for many years. Its sad that we will lose bits of the countryside, but we can only hope that in very sensitive areas, and/or places there is a lot of resistance that they choose to tunnel it as they plan to do through the Cotswolds AONB (aren't they?). There will still be a fair bit of leeway in the actual alignment I would imagine - I say this having walked 6, yes 6, 3 km sections of highway (doing transects 10m apart, so no small job!) for one infrastructure project so they could get the alignment that was the path of least resistance.
