It will never happen - they'll go for the cheap option of a few GSJs on the SDR.

Hi Jam35. I live in one of those houses that were hastily thrown up and rely on pebbledash for structural integrity above the Brynglas Tunnels. One of the houses that are now being threatened with demolition. Anyway I am officially inviting you to my disposable trash home in this godforsaken awful area so you can explain to my wife and child that their home that I have worked so hard to create is just a minor inconvenience to be demolished to make a road a bit wider.

So what's worse, significant disruption to yourself (not trying to understate any impacts on you) or significant disruption to the millions of people who use the M4 every year?

Well, if the propsed M4 to the south of Newport is now a complete non-starter, then they will have to do something about the Brynglas tunnels, sooner or later.

I'm sure that anyone living above the tunnels would be very handsomely compensated if the land above the tunnels was CPOed for a cutting scheme. Or perhaps a third bore would be easier and more practical given the amount of traffic the M4 now carries and the need to keep it open during works at Brynglas?

Upgrading Brynglas is a complete non starter, even a third bore just isn't going to be practical what with the temporary traffic management that would be required, logistical nightmare of building new structures in the already challenging environment. The practical and probably cheapest way to get 3 through lanes is to build a southern motorway around Newport and reroute the M4 onto the new alignment.

Been indulging in a bit of daydreaming.

How feasible is building a new eastbound carriageway a bit further north, via Woodlands junction for connections to Malpas, Cwmbran and Pontypool, and leaving the Brynglas tunnels - both of them - for westbound traffic only?

As I've suggested in another thread... heading west from Jcn24 , from the top of the hill build a french type viaduct right over the top of 25, 25a & brynglais and down on ot the hill after the tunnel .
