 The M4 is the key artery for the economy of South Wales. Without the M4, the economy simply wouldn't be able to grow or prosper. So it's essential that we make sure that maintenance is carried out when it's required and where it's required. Maintaining the M4 is essential to Wales and the UK economy. The Brynglas tunnels in Newport were built 50 years ago but are no longer compliant with current design standards. Further deterioration was caused by a fire in 2011 which caused significant damage to the structure. On the 20th of July 2016, work began to bring the Brynglas tunnels back up to European standards. These are mechanical and electrical repairs. It's a 40 million pound program to make sure that the M4 can run smoothly through the Brynglas tunnels. We know that there was a fire here in 2011. This work will remedy and rectify all of the damage that was caused by the fire. The project is to replace concreted panels on the lower levels which will protect the vehicles if they have impact to the side of the tunnel. We replace all the mechanical and electrical fittings and the lighting inside the tunnel. It stores some additional emergency protection measures with PA systems, fire sensors, heat sensors and put a new water meaning to allow the fire brigade to fight fires if there are any fires in the tunnel in the future. It's absolutely essential as well for investors to be able to see that Wales is open for business and I think demonstrating that by making sure that the Brynglas tunnels has the investment that it requires is very important. We're working on the US bridge in the days. We're working on Malpas Viaduct and we're going to put some cathodic protection elements in there and we're working within the Brynglas tunnels and on the night shift to minimise the disruption on the travelling particular. These closures will take place four nights a week from 8pm till 6am. This includes a limited number of short weekend closures. The Usk River Bridge and Malpas Viaduct needs essential maintenance. We need access under the Riverusk Bridge to tackle the joints, the hinge joints and expansion joints that need repair. Part of the work that we've undertaken under the bridge will involve hydrodemolition which is high water pressure demolition of the existing hinge joints. In order to do that we need to contain the water. It needs to go under extreme water containment to stop any pollution entering the Riverusk. We then contain the water and we'll pump the water then from the scaffold onto the riverbank where it will be treated before discharged to the sewage system. We have about 92% staff here from the local area. We're investing in our young engineers. We have an apprentice programme here where we currently employ two apprentices. We have two graduates, two undergraduates as well. Once completed, the tunnel, the bridge and the viaduct will be back up to standard and will continue to be effective and resilient. We're on track to see completion in spring of 2018 but there will be points at which the road works actually cease. So for example during the Six Nations and the Champions League final and other major events. So we're trying to keep disruption to an absolute minimum but this is essential work and it will help the economy and it will help communities in South Wales in the long run.
