Cambridge - Oxford Expressway

Cambridge - Milton Keynes - Oxford Expressway

In September 2018, the Department for Transport announced their preferred corridor for the proposed Cambridge to Oxford (via Milton Keynes) Expressway following recommendations from Highways England. This is the first of a number of key decisions that will be taken in respect of this locally and nationally important project.

In November 2017 the National Infrastructure Commission (NIC) published its report ‘Partnering for Prosperity: A new deal for the Cambridge-Milton Keynes-Oxford Corridor

As part of its recommendations the report proposed a new dual carriageway road – the Expressway - between Oxford and Cambridge. It offered three potential corridor options for the section between Oxford and Milton Keynes:

  • Corridor A - via Aylesbury
  • Corridor B - following the east-west rail route
  • Corridor C - existing A421 corridor around Buckingham

In April 2018 Highways England invited stakeholders to provide feedback on their preferred corridor.

In September 2018, Highways England announced Corridor B will be the preferred corridor, the first of a number of key decisions regarding this locally and nationally important project.

What happens next?

As shown in the timeline below, the next step in the process is route identification by the Department for Transport and Highways England, this will be open to public consultation in Autumn 2019.
