The Highways Agency has published a few details of the £1.5billion plan but has stressed that it is still working on the design of the scheme and the most appropriate solutions.However, the HA has made it clear that a bypass will be built to replace the existing A14 route through Huntingdon while the remainder of the A14 between Huntingdon and Milton will be upgraded. Two roads, one each side of the current A14, north of Cambridge will also be built for local use. The plans are also likely to include the removal of a number junctions along the upgraded road, along with improvements to other junctions. The scheme, which will feature 20 miles of new or widened road, looks similar to the plan scrapped in 2010. The plans do not mention whether the Huntingdon viaduct will be demolished but it would seem likely with the upgraded route bypassing the town. Tolling has all but been confirmed previously but more work will be undertaken to determine the best tolling solution, including how long the section should be, how users would pay and what the tariff should be, a spokesman said. The HA has said that details of expected benefits in journey time reliability and economic growth will be revealed in the autumn, when residents will also get to have their say on the route and its delivery in a consultation. A spokesman said: We know that construction is due to start in 2016, but in between then and now we have work to do. This includes further development of the scheme and consideration of mitigation measures, presentation of our proposals to the public and publication of a preferred route. At this stage it is too early to say whether the scheme would be built in stages.
