Question to the Department for Transport:

To ask Her Majesty’s Government, further to Written Answer by Lord Ahmad of Wimbledon on 17 March (HL6898), how many road tunnels worldwide there are of a comparable length to road tunnels planned underneath the Peak District; and for each of those (1) how long they have been in operation, (2) what traffic speed they operate at, (3) how many lanes there are and whether they have a hard shoulder, (4) what levels of air pollution are found within them, (5) what their construction cost was, and (6) whether they were delivered on time and on budget.

We are currently examining a number of corridors to identify potential links between Manchester and Sheffield. At this stage the precise length of any tunnel is unknown. The initial findings on the construction and maintenance of a potential tunnel were published in the Interim Report in November 2015. The next stages of the study will examine shortlisted options in more detail and will include the consideration of international best practice. The conclusions will be published later this year.
