Improving UK transport to boost the economy- what about the environment?

It looks likely that billions of pound will be spent on improving transport between major cities in the north of the UK, like Manchester and Leeds. These links would have to cross the Pennines, via a tunnel or through national park (the Peak district) these proposed changes/ improvements show a particular attitude to the environment. 




The latest plans unveiled in March 2015- indicate there are plans to build a road under the Peak district national park, however there are still the earlier plans above where people are propsing train tracks through the peak district- this will lead to conflict, regardless of the decision that is finally made- conservationists will not want the natural landscape interrupted and workers will ant the quickest route possible, tax payers will want the cheaper option. So what will be the end result?
