The preferred route of a new road linking Cambridge and Oxford has been announced.
Transport minister Jesse Norman said the Expressway will run alongside the planned East West rail line, to give consumers "a variety of road and rail travel options".
The Department for Transport said scrutiny of three options revealed that a central corridor would offer the most benefits to the region by providing better links to jobs, education, leisure facilities and health services.
The road is expected to cut up to 40 minutes from journeys between the M4 and the M1. The design of the road will be put to public consultation next year. It is scheduled to be open to traffic by 2030.
