Question to the Department for Transport:

To ask His Majesty's Government, in the light of comments by the Secretary of State for Environment, Food and Rural Affairs, reported in New Civil Engineer on 4 March, that spending "vast sums" on High Speed 2's bat tunnel is "ludicrous", why they have allowed construction to continue at a cost of £119 million.

The cost of the Sheephouse Wood bat structure is £95m in 2019 prices. It has been designed and constructed to comply with species protection laws as they currently stand, and to fulfil the requirements of the licence issued by Natural England in 2023. Abandoning construction in advance of any changes to the relevant legislation would be a breach of the conditions under which the new railway can be legally operated, and a presumption of the will of Parliament. Furthermore, and in common with much of the civil engineering structures for HS2, construction of the bat mitigation structure is well advanced and forms part of an integrated design for the railway in the Calvert area. In such circumstances, decommissioning and removing the elements of the structure already built, and redesigning and then constructing an alternative scheme for this section of railway would - at this stage in the construction schedule - cost more than completing the existing structure.
