TfL Ref: 2809-2122

Thank you for your request received by Transport for London (TfL) on 10 March 2022 asking for information about the sound barrier on the A102 Blackheath Westcombe Ward, Greenwich.

Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy. You asked: I would like to know what plans you have in place and what the cost will be for a sound barrier along the stretch of road bordering the above-named ward. Also, do you have a map of these plans?

I can confirm that we hold some of the information you require.

Information on our plans for a “sound barrier” along the A102 within the Blackheath Westcombe Ward along with a map are already available as part of our recent public consultation. Please visit the site to view the consultation information and our final report.

In summary, we have undertaken investigations at the site identified in the Silvertown Tunnel Development Consent Order (DCO), including: noise monitoring, sub surface infrastructure, structural investigations for supporting structures, ground and land investigations. We also created a noise model for the area and used it, along with many other variables, to evaluate options and select our preference. We presented this option to residents with properties alongside the proposed barrier which are most impacted by the noise, visual appearance and construction/whole life maintenance activities. We asked for their opinion on our plans and some specific views such as the length of the barrier to the south and colour of the timber option.

We are committed to working closely with residents throughout the ongoing design process to identify any specific issues that can be solved by engineering to minimise impact of the works and ensure the scheme benefits are delivered. The final design will be subject to usual planning regulations. Alongside design and planning approval, we will need to undertake activity ahead of constructing the noise barrier including landowner agreements, procurement, applications for traffic management orders and other permits. Subject to this proceeding without delays, we plan to be on site to start the works in 2023.

The high level programme is:
Noise Barriers Plan Date
Completion of Feasibility Q1 2022
Concept Design Q2 2022
Commercial Procurement - Detailed Design and Construction Q4 2022
Detailed Design Q2 2023
Notifications Q3 2023
Start on Site Q4 2023
End on Site Q1 2024

We do not hold details of the cost of the works - as you’ll note from the above, we intend to undertake, but have not yet commenced, a commercial tender for a contractor to complete the detailed design and construction of the barrier. Details of the contract would be published in line with our regular processes and will be available on our website.

If this is not the information you are looking for, or if you are unable to access it for any reason, please do not hesitate to contact me.

Please see the attached information sheet for details of your right to appeal as well as information on copyright and what to do if you would like to re-use any of the information we have disclosed.

Yours sincerely
