Cleveland Bridge: Weight Limit — House of Commons, 2020-11-17
Topic: Environment
Wera Benedicta Hobhouse (Liberal Democrats, Centre to centre-left): Good evening, Madam Deputy Speaker. I am very grateful to have been granted this debate on the future of Cleveland bridge, which is of high importance for my constituents in Bath. I look forward to the Minister’s full response Cleveland bridge is a grade II* listed structure. It forms part of the character of Bath’s UNESCO world heritage status. It is worth reminding fellow hon. and right hon. Members that Bath shares its unique status only with Venice. Not just parts of our city but the whole city and its setting are a world heritage site. The protection of the city as a whole is of national importance, and it should not just be the citizens of Bath and the council that are called on to safeguard this treasure for future generations There is another aspect to this debate. Bath is a city identified as suffering from illegally high levels of air pollution, and it has been ordered by the Government to bring pollution levels down to the required legal minimum. The council has worked hard to develop a strategy in response. The route with one of the highest levels of air pollution is London Road leading towards Cleveland bridge Cleveland bridge links the north and the south of the city over the River Avon just a short walk from the city centre and is surrounded in all directions by listed architecture. Unfortunately, it is part of the primary road network and therefore has to be open to all traffic. The bridge consists of 19th-century ironwork with a 1920s concrete deck, but the weight of modern heavy goods vehicles is shaking the bridge to bits. Heavy traffic on the A36 and the alternative A350 has been an ongoing source of tension for many residents for many years. Not only are there issues at Cleveland bridge, but just a few miles away at the village of Limpley Stoke, the A36 suffers from regular landslips. It is also true that the A350 has issues and needs better infrastructure In 2009, Wiltshire Council attempted to put in the Westbury bypass to improve the A350 corridor. That was supported by Bath and North East Somerset Council, but the implementation of the plan was stopped by a public inquiry in 2009. In 2012, Bath and North East Somerset Council attempted to put a weight limit on Cleveland bridge. Objections were received from Wiltshire and Highways England, leading to a judicial review. Bath and North East Somerset Council was told it could not impose a reduced weight limit of 18 tonnes It is of note that the 2012 ruling states that "we are conscious of Bath and North East Somerset’s important concerns about local air quality. The Department is not, in line with PRN guidance, commenting on the air quality aims of the proposed scheme." Eight years on, and especially since the challenge to Government by ClientEarth, the goalposts on air quality have completely changed. It is time that the Department for Transport commented on air quality in Bath when it comes to the A4/A36 route over Cleveland bridge It is clear that from the south coast to the M4, there is a shortage of suitable routes to take north-south traffic. For example, routes travelling east to west move at approximately 60 mph, but north-south routes travel at 30 mph. The impact is not just about lorries going through villages, but the loss of economic activity and efficiency Over the past few years, Wiltshire Council, Dorset Council and Bath and North East Somerset Council have formed an alliance. They recognised that, however much investment they made as local authorities, it would not be enough to fund the improvement of any one route. Additionally, if any authority favoured a particular route, it would become politically very challenging. I thank all colleagues across those three local authorities for the work they have put in so far, working together on a complex set of circumstances The alliance threw the question back to the Government and asked for an economic study to take place, and the relatively simple question was: which is the best route, and how do we improve it? This is now called the strategic study and is being undertaken by Highways England as part of its road improvement strategy. Highways England and the Government now have ownership of the issue. The A350 has been selected to be looked at in-depth I am grateful to the Minister, Baroness Vere from the other place, for responding to me in her letter on 22 October. She wrote that the improvement strategy will review the case for adopting the A350 corridor as the main strategic route in place of the A36/A46 and will consider the case for trunking or detrunking these key roads. The study alone will take until approximately 2023 to complete and then, if adopted, the third phase of the road improvement strategy will provide the framework to implement and pay for the necessary upgrades. In the meantime, Cleveland bridge will be closed for much of next year as urgent repairs to the structure are carried out. I am grateful to the Department for Transport for making funds available As I said before, Cleveland bridge is a grade II* listed structure. In their 1992 report, the engineers who carried out the last set of repairs stated that they did so on the understanding that the then local authority would exclude the heaviest vehicles. That never happened. In fact, it got worse The challenge of a listed heritage asset is that you have to work with the structure as it is listed. You cannot replace the Victorian ironwork—because it is listed. You cannot replace the 1920s concrete deck—because it is listed. You can only repair and strengthen them, but they will never be stronger than when they were new, and when they were new, they were never expected to carry the very heavy vehicles that are being used today. The innovation of the bridge’s design, in both the early 19th and 20th centuries, is recognised in its listing, but those designs never envisaged that the bridge would be on a modern primary road network, with all that that entails.
