The A15 between Glinton and Gunthorpe is not a trunk road and so is the responsibility of Peterborough city council as local highway authority. Their second Local Transport Plan, published in March 2006, currently being assessed by the Department for Transport, proposes incremental improvements beginning with dualling the section between junction 21 (Gunthorpe) and junction 20 (Werrington). The Department for Communities and Local Government announced approval on 3 August 2006 of Growth Area Funds to the sum of £5.85 million for this work. The target date for completion is March 2008.
