in 2011 the government announced an 'a14 challenge' inviting people to present proposals for the route. the revised scheme, now known as the 'a14 cambridge to huntingdon improvement scheme' involves widening of the a1 between brampton and alconbury, a new huntingdon southern bypass, widening of the existing a14 from swavesey to milton, and a new local access road between swavesey and girton. the a14 viaduct in huntingdon town centre will become redundant and will be demolished. in november 2012 it was reported that the scheme might be back on a fast track to implementation and it was mentioned in the june 2013 spending review. the project was approved by the secretary of state for transport in may 2016. work is due to be complete by march 2021 at a cost of £1.2-1.8b.
