To ask the Secretary of State for Transport, pursuant to the Answer of 26 April 2018 to Question 138336 on Roads: Stonehenge, if he will publish the terms of reference of the archaeological surveys planned by the independent Scientific Committee; and when he plans to publish the results of those surveys.

The Terms of Reference of the archaeological surveys for the A303 Stonehenge project, in relation to works affecting the World Heritage Site (WHS), are set out in a series of Written Schemes of Investigation (WSIs).

WSIs are produced for each site on the scheme before any work is started, and are working documents that will undergo a number of updates throughout the lifetime of the surveys to encompass additional requirements identified as the work progresses. There is also a high level overarching WSI for the whole scheme. The initial WSIs will be published on the Scientific Committee’s website by the end of this month (http://a303scientificcommittee.org.uk).

The final iteration of each individual WSI will also be published alongside the survey results, to outline in full the investigations that were found to be required.

The reporting of the surveys in the WHS is likely to be finalised in the autumn when it will be published on the Scientific Committee’s website, alongside the already published archaeological survey reports that have been completed to date in relation to the WHS.
