Now, the commission's work has already begun. I've had incredibly constructive discussions with Lord Burns about the work that's being undertaken to date by the Welsh Government and how he and his commission will take the work forward. We are examining all short-term measures that are available to alleviate congestion. I'm pleased that we are able to introduce additional patrol services and breakdown recovery services. These will not come without cost, of course; these are expensive services, but they are now tried and tested. They were deployed first on the A55 as part of the A55 resilience work, and they are now proven to work.

I must add that not all of the money that was allocated to the black route is available for a road-based solution or for interventions purely on the M4 because, of course, one of the reasons why the First Minister decided not to grant the Orders was because it would have drawn capital from other vitally important social infrastructure. However, the First Minister has already been clear that the recommendations put forward by the commission will have the first call on funding set aside by the Welsh Government to resolve the issues that we see on that part of the road network.

But we've also been clear with Members that those solutions must represent good value for money. It will be for the commission to consider all solutions. We will not be entertaining any pet projects, as I said in my written statement, outside of the commission's work. Whilst there will always be competing demands for funding, we are clear that delivering sustainable solutions for the significant challenges along this transport corridor is a top priority, and I can assure Members that the money spent since 2013 developing the proposals for the M4 project will not be wasted and will be put to good use by the commission, making sure that it is fully informed in terms of transport modelling, in terms of environmental surveys and all the other factors at play right across the region.

I recognise that the figure attached to the development cost of the proposed black route is significant, but it does represent something in the order of just 6 per cent of the overall project cost that was estimated. And that, as I've said already in this Chamber, compares very favourably to other projects across the UK. You only need to look at development costs of projects such as HS2 to appreciate that you cannot deliver a major infrastructure project in the western world without incurring significant development costs.

We've also been very clear in stressing that this project is absolutely unique in terms of the scale and in terms of the impact on the site of special scientific interest, and that, therefore, it had to be considered in its own right. Since we presented, I think, a very compelling case, there's been a declaration of a climate emergency, a greater understanding and appreciation that we need to act now, that we need to be more responsive and more responsible, and, therefore, the bar has been raised.

I know that other schemes have been highlighted recently and a fear that they will be lost as a consequence of this being seen as having set a precedent. That is simply not the case; all of those programmes will go ahead. Indeed, the Caernarfon-Bontnewydd bypass is going ahead. We are proceeding with consultations on improvements to the A483 this month. Work on the Flintshire corridor of the A55/A494 will be proceeding this summer with further modelling work, Welsh transport appraisal guidance work and further consultations and meetings with local stakeholders. Other road projects across the length and breadth of Wales are still in the pipeline to be delivered, and this does not shift our position on those.

We also have some incredibly exciting and bold plans for public transport here in Wales: from the £5 billion plan that we've developed, through Transport for Wales, for the new and transformational rail franchise and metro; to major legislation that will help us to re-regulate the bus network; to, of course, the biggest investment we have ever made in active travel. There is a huge amount of exciting work taking place right across Wales that I think will inspire, will encourage and will enable modal shift, which is so very important. Dirprwy Lywydd, we are committed to taking an inclusive and collaborative approach to finding innovative, affordable and sustainable solutions in the shortest possible timescale, and we look forward to working with Members and stakeholders in conjunction, of course, with the commission, to meet that need.
