More than half a million people across Middle England will have their lives affected by the construction of the HS2 rail project, campaigners are claiming.
The Campaign for the Protection of Rural England (CPRE) is warning that life in towns and villages up to 25 miles from the rail route will be disrupted by the movement of construction vehicles while the line is being built.
The organisation is publishing its analysis of the impact of the project, in the form of a series of maps, based on information it has obtained from HS2.
According to advance details released to The Mail on Sunday, towns along a 40-mile wide corridor - such as Thame in Oxfordshire, Princes Risborough and Beaconsfield in Buckinghamshire, and Leamington Spa in Warwickshire - will be affected by the millions of extra lorry journeys.
When it is built, some of the country's most tranquil areas will be blighted by train noise of up to 95 decibels near the track - the equivalent of a Tube train - from up to 16 trains an hour travelling at 225mph, the paper said.
CPRE senior transport campaigner Ralph Smyth strongly criticised HS2 for its reluctance to hand over the information. "It is not acceptable that it took a charity to uncover this and let up to half a million people know that they will be affected by this project," he told The Mail on Sunday.
"We asked HS2 for all the data on the construction and the scheme itself. The draft Environmental Statement was published on May 16 and that's when we asked for the full data. I was chasing the data all the time and they just kept saying 'it's coming by email' or 'it's in the post'."
An HS2 spokesman told the paper: "We have considered all construction access routes as part of the development of the draft Environmental Statement on which we consulted earlier this year.
"The consultation was open to all members of the public to respond and express potential concerns or suggest alternatives. We have sought to provide construction access with minimal disruption and will continue to work with local communities to take on board their views. In developing the subsequent formal Environmental Statement, we will be considering how we can further reduce any adverse impacts."
The spokesman added: "HS2 Ltd is still developing transport routes for the construction of the line, accordingly it is not possible to definitively say how the road network will be used. The information supplied to the CPRE is based on the most accurate assessment, given the progress of the line's design at the time."
