High Speed Rail (London-West Midlands) Bill

Is the Minister aware that, about 10 years ago, his department constructed two bat bridges in Cornwall, at a place called Dobwalls bypass—which I go under most weekends. At that time, they cost £300,000 each and I asked a load of Written Questions asking how many bats used it and how many did not bother and just flew across the road. I got the number of bats that used it, but not the ones that flew across the road. Do we really need more of these bat bridges?
