View of Stokenchurch Gap

Stokenchurch Gap.
The cutting is mainly through the Upper Chalk, with some Middle Chalk seen at its base. The cutting is a Site of Special Scientific Interest of geological importance. It provides the best Coniacian section in central England.

The curved route of the cutting was designed to mitigate impact on the skyline, and to fit the local topography.[citation needed] The construction of this section of the M40 (junctions 5–8) was at the time extremely controversial, since the cutting through the Chiltern Hills was driven through the middle of the ecologically-important Aston Rowant NNR. Conservation groups were appalled at the unexpected decision of the inspector at the public inquiry to reject their claims that the national nature reserve designation implied a fully protected landscape which should in no circumstances be damaged. Their alternative proposals for a tunnelled solution, or a route on-line with the existing A40, were rejected.

The M40 motorway passes through the reserve, where a cutting, the Stokenchurch Gap, drops the motorway down onto the Oxfordshire plain between Junction 5 Stokenchurch and junction 6 Watlington. This section of the "Midlands Link" motorway opened in 1974 after a Public Enquiry. The event helped to motivate conservation groups to oppose infrastructure projects that would damage protected natural habitats, such as the M3 cutting through Twyford Down near Winchester, which could have been protected by tunnelling.
