A40 improvements

We’re improving the A40 between Witney and Oxford to deliver safe and reliable travel options for those who rely on it for work, leisure and economic success.

About the A40 improvements

We’re investing in six major schemes, which will deliver a new park and ride, an extension of the dual carriageway around Witney, new bus lanes and junction improvements. 

Our proposed plans to address traffic and transport issues will result in better transport links, the creation of new jobs and housing, reduced emissions, and more sustainable travel options.

What you can expect

Two of the schemes within the A40 improvements work (A40 Oxford North and Eynsham park and ride) have already progressed past consultation.

The initial proposals are now complete for the A40 HIF2 Smart Corridor (Duke’s Cut, integrated bus lanes and the extension of the dual carriageway) and Access to Witney.

On 21 July, Cabinet approved the preferred option proposals for the A40 HIF2 Smart Corridor (Duke’s Cut, integrated bus lanes and the extension of the dual carriageway) and Access to Witney projects. These options were developed taking into account output from the online public engagement events and liaison with key stakeholders.

The proposed plans to address traffic and transport issues will result in better transport links, the creation of new jobs and housing, reduced emissions, and more.

This is a major step forward to starting the works to improve the A40 in Oxfordshire.
