We have done detailed site assessments, surveys and acoustic modelling. This is to identify where noise barriers could be installed and where they will provide the greatest benefit in reducing noise.
We have identified eight sites between Wooburn Moor (junction 3) and Stokenchurch (junction 5). We are working on a detailed design of noise barriers for these locations.
We have also recently resurfaced a 4.3 mile (7km) section of the M40 between Adwell (junction 6) and the A40 Oxford spur (junction 8) using a quieter surfacing material. This has successfully reduced noise levels on this section.
We have prepared an online exhibition. It provides information on the potential location of the new noise barriers, together with proposed designs and likely impact on current noise levels. We welcome your questions and feedback on the scheme, which can be provided online or face to face at a local Public Information Event to be held at Wycombe Leisure Centre on 30 June 2017.
Why we need this scheme
Traffic levels on the M40 are having a significant impact on the quality of life of the communities living along this route. On the 20mile (32km) section between Loudwater (junction 3) and Wheatley (junction 8) there are a number of sizeable communities and 21 identified Noise Important Areas.
We are committed to reducing environmental impact and improving the quality of life for local communities living within close proximity of our road network.
We recognise that we have a responsibility both to road users and to those affected by the operation of our network. We are working hard to reduce the negative impacts of our roads and wherever possible enhance the quality of the surrounding environment. Our current five year Roads Investment Programme sets out our commitment to reduce noise in at least 1,150 Noise Important Areas across our network by 2020.
The scheme in detail
We have been working closely with the M40 Chilterns Environmental Group, representing the local communities together with Wycombe and South Oxfordshire District Councils, to identify effective solutions to reduce noise and improve the quality of life for those living along this section of the route.
The scheme originally involved trialling innovative, energy-generating noise barriers mounted with solar panels. Although the outcomes of early assessment work concluded that these types of barriers would be currently unsuitable for this section of the M40, this work has proved valuable in development of robust assessment and evaluation criteria that can be taken forward when considering use of â€˜photovoltaicâ€™ noise barriers at other Noise Important Areas across the network.
We are now progressing the M40 scheme through our National Noise Programme, with the assessment and detailed design of more conventional noise barrier solutions.
With this scheme, we aim to reduce the impact of traffic and road noise levels from the M40 upon the quality of life for local communities along the route.
