Key routes in England are to be upgraded as part of a programme of works worth a mighty €33.9 billion (£30 billion) plan from 2020 to 2025. This five year plan from Highways England will see many of the major A road routes being reclassified as A(M) expressways. These will resemble motorways in many respects, with new on and off ramps and additional lanes being constructed. The A14 stretch between Cambridge and Huntingdon will be one of the first stretches to be upgraded in such a fashion. This is an important upgrade as this section of the A14 connects the M11 motorway with the A1(M) route and is notorious for congestion and long delays. The A1 to the north of Peterborough, the A3 between London and Portsmouth, the A12 in Essex, the A50 between Stoke and Derby and the A303 between the M3 and M5 will all become expressways. For the A303 to be upgraded this way will require the long-awaited and potentially controversial Stonhenge Tunnel bypass to be completed.
