Noise barriers on the A102

Consultation has concluded

Between 26 October and 23 November 2021 we held a public consultation on proposals to install a noise barrier on the A102 to reduce the impact of traffic noise on properties in the Siebert Road, Invicta Road and Westcombe Hill area.

We received 16 responses to the consultation. Thank you to those who took part. We are now considering the feedback we received and this will inform our ongoing design work. Once the design is completed we will be in touch with residents directly to share our plans for the finalised noise barrier. We will also respond to issues raised

Introduction

We are asking for your views about the noise barriers we plan to install on the A102 to reduce the impact of traffic noise on properties in the Siebert Road, Invicta Road and Westcombe Hill area.

We spoke to residents at a virtual meeting in February 2021 and the feedback helped us ensure our options study considered the things residents said were important. Before we finalise our plans we would like to understand how our proposals will affect local people and obtain your opinions, particularly around the colour of the noise barriers and how far they should extend in a southerly direction towards the junction with Charlton Road.

The noise barriers will be situated alongside the A102 from the railway viaduct towards the junction with Charlton Road, in order to reduce the traffic noise to residents most effectively.

Background 

The Silvertown Tunnel scheme is a planned road tunnel under the Thames between Silvertown and the Greenwich Peninsula. The scheme includes the introduction of user charging at the Silvertown and Blackwall Tunnels, and a transformative new cross-river bus network. This will address the longstanding issues of congestion, poor reliability and a lack of resilience at the Blackwall Tunnel, and allow us to better manage cross-river traffic; encouraging people to travel at less impactful times, in cleaner vehicles or to switch to public transport where possible.

As part of the Silvertown Tunnel scheme, Transport for London has committed to a number of enhancements for the local communities either side of the river, including the installation of noise barriers to address pre-existing noise along the western edge of the A102, between the junction with the B210 Charlton Road and the railway viaduct.

Location of the proposed noise barrier 

A map showing the proposed barrier location can be found in the 'Documents' section. The dotted line close to Charlton Road is where there is still some flexibility about the extent of the barrier.

Our Proposal

We are proposing to install free-standing barriers on most of the route between Westcombe Hill viaduct and Charlton Road. At the Bramshot Avenue Subway, we intend to attach the noise barrier to the subway structure.

The barriers will be installed on TfL and Council owned land adjoining the highway whenever possible. A potential exception is between 55 and 113 Westcombe Hill, where an option to locate the barrier in a layby of the A102 is also being explored.

The barrier is proposed to be 2m high along Westcombe Hill Road and Siebert Road and along part of Invicta Road, following extensive studies from our acoustics experts to ensure a reasonable reduction in noise at this location. The height is proposed to increase to 3m at the southern end of Invicta Road. This is to enable the taller buildings and flats on higher levels in this area to also receive the benefit of the noise barrier.

A diagram showing the proposed barrier location can be found in the 'Documents' section.

Following our feasibility studies, we propose that the barrier will be made from timber as it can be easily installed, made sustainably and is most cost effective. It is a popular choice for this type of barrier due to its high performance.

Our proposal is for the barrier to be in a natural, light brown wood colour but we would like to hear from residents about their preferences for the colour of this barrier.

Dark green, dark red or brown, could also be an option, if residents would prefer these colours. However, wood staining is more expensive both for construction and replacing panels in the future so is not our favoured option.

We are aware that residents have previously proposed a green wall. We carefully considered whether this would be possible, but we have concluded that it would be more expensive and challenging to install and would require regular maintenance, requiring regular access to your properties. It would also be less effective in reducing noise at this location.

The images below, from other locations, show how a noise barrier may look if made from timber in its uncoloured form.

Extent and length of the barrier 

We are considering some options regarding the extent of the proposed noise barrier.

One option could be to finish the barrier at the junction with the B210 Charlton Road Overbridge and another could be for the barrier to end earlier between Wentworth House and 2-12 Invicta Road. We would like to hear from residents on Invicta Road about their preferences.

Finishing the barrier at the junction with the B210 Charlton Road Overbridge will require more vegetation clearance but would offer the greatest noise reduction to the properties in that location, notably Wentworth House.

Finishing the barrier earlier, between 2-12 Invicta Road and Wentworth House will require less vegetation clearance but would also offer less noise reduction to the properties in that location, notably Wentworth House.

The images below show the vegetation at the top of the embankment that could be affected.

Next steps 

Following the consultation, we will publish the results as soon as possible and the feedback received will inform our ongoing design work. Once the design is completed we will also be in touch with residents directly to share our plans for the finalised noise barrier.

Following this, we will need to do considerable work ahead of constructing the noise barrier, including procurement procedures, traffic management orders planning and gaining other permits. Subject to this proceeding without delays, we plan to be on site in 2023.
