Turweston and the proposed HS2
The information on this web page was prepared in 2012. It has not been updated since then and so it may no longer be correct.
Below you can see a map from the Ordnance Survey. After a short while, a coloured line will appear superimposed onto it. This line shows the route of the proposed HS2 near to Turweston. The line should be accurate as it is derived from data for the post consultation route that was published by the Department for Transport in January 2012.
This line is coloured red for cuttings, yellow for embankments, blue for viaducts and green for green tunnels.

South Northmaptonshire Council have published ten maps showing how the HS2 crosses their region. Here are links to the map covering Turweston to Brackley East. and the map covering Brackley East to Radstone.
Recent changes to the route
A report entitled Review of possible refinements to the proposed HS2 London to West Midlands Route says: At Turweston the addition of a short green tunnel would be significantly more sustainable, reducing landscape and visual impacts as well as impacts on accessibility and the local community.
The Post Consultation Route Engineering report notes: Following client review, it was proposed that a green tunnel be provided at Turweston. The possibility of raising the alignment in this area to reduce the scale of the cutting was also considered but found to be impossible without increasing the height and hence visual and noise impact of adjacent embankment and viaduct sections.
Later, it recommends: From south of Turweston to mid-way between Radstone and Greatworth, the Post Consultation Route would for the most part be identical to the Consultation Route. On the east side of Turweston however, where the route would be in a long deep cutting, a 100 metre section of green tunnel would be provided where the road to the former airfield crosses the route. This would reduce severance and mitigate the visual impact of the cutting on the village.
Jargon
- The consultation route is the route that was proposed prior to public consultation. It was published on 28 February 2011.
- A green tunnel is essentially a deep cutting with a tube put into it, over which grass, trees and soil are placed. It is not as deep as a normal tunnel, and it is much cheaper to construct. This is the definition given on a BBC web page. Here is a link to a photo of a green tunnel.
- The post consultation route is the route that was proposed after the public consultation period. It was published on 10 January 2012.
