These documents are intended to help explain the Silvertown Tunnel scheme in more detail to a non-technical audience. Our consultation booklet provides an overview of all the key elements and effects of the scheme.
The 'Guide to the consultation documents' sets out a plain English summary of the purpose, methodology and main findings of each of the technical reports.
The following documents outline our assessment of a range of alternative options for addressing the challenges at the Blackwall Tunnel and what effect the Silvertown Tunnel scheme might have on users of the River Thames.
The 'Statement of community consultation' explains other ways you can access the documents on this page, as well as how to contact us and register your views.
These reports are part of a suite of documents that support the statutory public consultation for the Silvertown Tunnel scheme. Among other issues they set out the impacts and benefits of the scheme.
Preliminary case for the scheme
Sets out how the Silvertown Tunnel scheme was developed and the main alternatives that were considered. It outlines the benefits of the scheme and how it meets its objectives.
Also includes in Appendix C our 'Preliminary monitoring and mitigation strategy'. This sets out how we would monitor traffic, air quality and noise levels.
Preliminary charging report
Outlines the user charging proposals for the Blackwall and Silvertown Tunnels and sets out TfL's reasons for proposing user charging, the proposed structure and implementation of the charge and the objectives TfL would take into account in setting the charge and varying it in the future.
Preliminary transport assessment
Details the main transport impacts of the scheme for all forms of travel and what measures would be taken to minimise any adverse impacts. It also examines road network impacts and impacts on public transport networks and walking and cycling.
Preliminary design and access statement
Sets out the outline scheme design. It demonstrates why it is a suitable response to the site and its setting, taking into account existing and future planned development and that it can be adequately and safely accessed. It also sets out the design principles which will inform the detailed design, providing examples of how the scheme may develop in the future.
Preliminary engineering report
Explains the proposed design of the scheme from an engineering perspective and sets out the assumed method of construction.
Preliminary maps, plans and drawings
Displays the physical elements of the scheme. It includes:
- A location map
- Plans showing the proposed works and how these tie-in to the existing highway network
- An outline of the land required for the safe construction and operation of the scheme
- A series of engineering cross-sections through the tunnels and tunnel approach roads
Preliminary environmental information report (PEIR)
Describes the scheme and the main alternatives considered. A non-technical summary of the PEIR is also available - it summarises the PEIR in plain English.
The PEIR sets out the environmental baseline information, provides an assessment of likely environmental effects and, where necessary, describes mitigation measures that would avoid, reduce or offset the adverse environmental effects.

Preliminary sustainability statement
An appraisal of the scheme's sustainability credentials. It assesses the scheme using a number of methods, including TfL's Sustainability Assessment Toolkit.
Preliminary energy statement
Assesses the opportunities for minimising CO2 emissions during construction and operation of the tunnel. It considers the implementation of passive design measures, energy efficiency, and low and zero carbon technologies.
Preliminary equality impact assessment
Assesses the scheme's potential impacts on equalities groups. The assessment outlines potential mitigation measures to achieve a positive impact.
Preliminary health impact assessment
Assesses the scheme's impact on human health and wellbeing. The HIA seeks to recommend mitigation that may improve health and reduce inequalities in health.
Preliminary outline business case
Sets out the outline business case for the scheme and assesses:
- Its strategic need and compliance with public policy
- Its value for money
- Whether it is commercially viable and can be financed
- Whether TfL has the capacity and ability to deliver the scheme
We have also included a number of appendices to the outline business case. These consider:
- The extent to which the scheme could affect specific social groups
- The social impacts the scheme could bring about
- The analysis undertaken for the scheme's economic case
- An assessment of how the scheme would affect economic activity at a local, sub-regional, and London level
These reports contain supplementary information about the Silvertown Tunnel scheme or its impacts. We have published them because they are referenced in some of the reports included in the Main case section.
Health impact assessment (HIA) scoping opinion
Sets out the matters that were identified as relevant for consideration in the HIA and a proposed scope and methodology. This was consulted on with relevant health related stakeholders and the results of this informed the development of the preliminary HIA.
Silvertown Tunnel business survey
We commissioned market research to provide updated information on the opinions of businesses on the Silvertown Tunnel scheme.
