Expansion plans for Milton Keynes
Milton Keynes is a purpose-built, 'new city' in South East England. It is located about 45 miles (75 km) north west of London and approximately midway between Oxford and Cambridge. With other towns it forms the unitary authority of the Borough of Milton Keynes.
A421 road
The Oxford to Cambridge Expressway is a proposed grade-separated dual carriageway between the A34 near Oxford and the A14 near Cambridge, via (or near) Milton Keynes. The proposal aims to establish this route by linking existing roads and building new ones. The case for its creation is examined in a Strategic Study for the Cambridge – Milton Keynes – Oxford corridor, published by National Infrastructure Commission in November 2016. The NIC sees the road as being of national strategic importance by providing an outer orbital route around London, linking Southampton, the M3, M4, M40, M1, A1, A14/M11 and Felixstowe.
