Question to the Department for Transport:

To ask Her Majesty's Government whether they commissioned the Institution of Civil Engineers to independently review the options for the HS2 tunnel approaches to Euston; if so, when they will publish the report of that review; and where that review will be published.

In response to the Oakervee Review conclusions, the Department for Transport has commissioned a study looking into the design and construction efficiency of the future Euston station as a whole including considering options to simplify the HS2 approaches into the station.

As part of the study, an independent panel of experts was convened with the support of the Institution of Civil Engineers to consider the proposed design of the HS2 approach tunnels into the station. The study is ongoing and the selection of an optimised design and delivery strategy will include consideration of the work carried out by the Institution of Civil Engineers and all relevant engineering and operational factors. A further update on the outcomes of this work will be reported in the next HS2 Parliamentary Report.
