Transport secretary Grant Shapps has announced the formal cancellation of the £3.5bn Oxford to Cambridge expressway.
The road was planned to run from Oxford to Cambridge via Milton Keynes but Shapps said analysis had revealed the project did not provide value for money for the taxpayer.
Shapps said: “The Oxford-Cambridge Arc is home to cutting-edge research, globally-renowned science and technology clusters, and some of the most productive places in the country – we want to make sure it has transport fit for such an important region.
“Our analysis shows the expressway cannot deliver such links in a way that provides value for money for the taxpayer, so I have taken the decision to cancel the project. But we remain committed to boosting transport links in the area, helping us to create jobs and build back better from Covid.
“We will continue to work on more targeted, localised road improvements to boost transport in the region, alongside the transformational East West Rail, in which we have invested £760m to deliver the next phase.”
