My hon. Friend no doubt has constituents who will have experience of that overflow traffic in exactly the same way that I do. I will talk a little later on about how the A5 acts as a relief valve for the M6, but if people cannot move along the A5 in the way that they need to, the danger is that they will seek alternative routes that take them off the trunk road network.
I have already mentioned that the local councils are coming together, demonstrating their desire to grow and develop their employment and housing offer. By investing in this road, central Government can help those councils to meet their growth needs by facilitating a safe, reliable, efficient and resilient A5.
With that bit of resilience in mind, I will talk about the importance of keeping the traffic moving, to which my hon. Friend just referred. We know that there are often many planned and unplanned incidents on the M6, and that when the M6 comes to a halt many vehicles turn to the A5. Indeed, over the last 36 hours, there have been a dozen or so different lane closures on the M6 due to either maintenance work or incidents on the road.
In those circumstances, when traffic migrates from the M6, the A5 struggles to cope in certain situations and creaks under the weight of the additional traffic. That is often compounded by operational issues on the A5 itself, which in turn creates significant problems on local roads, as my hon. Friend has just referred to, with traffic dispersing because drivers seek alternative local routes.
One of the reasons for the lack of resilience, and it is the core of our call to the Minister today, is the variation in the standard of the road along the corridor. It is, in parts, recently constructed dual carriageway, with a great road surface that enables the road to work well. However, in other parts it is a windy A road, a single carriageway with double yellow lines, where the traffic really slows down. It is that variability that is at the heart of the challenge facing the road’s users. That situation is aggravated, as the Minister may know, because the road is constrained by old canal and railway bridges. That creates congestion and slows down journey speeds, impacting businesses and commuters, and even impeding emergency vehicles. Along with my colleagues here today, I am arguing that what we really need is the complete dualling of the road between the M1 junction 18 and the M6. That is our long-term objective.
On safety, one of the key objectives of National Highways is to reduce casualties on our roads. Sadly, the pressures on the A5, along with the development I mentioned, mean that the road has become a barrier to road users safely accessing economic hubs and other parts of the road network. I spoke about how that has impacted on congestion when incidents occur on other strategic roads but the safety of the road itself is impacted. Many of the junctions—be they roundabouts or road turnings—were not designed to cope with the levels of traffic that they are experiencing. We know that as congestion increases, so does the risk of collision. It can be caused by driver frustration or the limited safety provisions on the single carriageway sections of the road.
Along the corridor, that is, the 53 miles between the M1 and the M6, about a quarter of collisions occur during evening peak hours. Significantly, data demonstrates that the nature of the road, which is of a mixed standard, moving from dual to single carriageway sections with a large number of roundabouts, contributes to the number of collisions. Indeed, across all sections of the road, approximately 40% of the accidents that lead to personal injuries occur at roundabouts, compared with a national average of 10%. That is based on data provided by the police.
The historically fragmented nature of the A5, both through its construction and its inconsistency, can be seen as the heart of the issues with the road. Further or full dualling of the A5 will improve the overall capacity and resilience of the road while improving its safety and performance.
