The route linking the West Midlands and the north of England to East Anglia and the container ports of Felixstowe and Harwich is incredibly important and incredibly busy. And yet it didn't exist in any coherent form until about 1992 when the A14 popped into existence.
A14 Fen Ditton - Ellington 26 April 2017
An upgrade of the A14 route between Cambridge and Huntingdon, and in particular the stretch connecting the A1 and M11.
The improvement includes construction of a new dual-three lane route south of Huntingdon to bypass part of the existing road, with the remainder upgraded and widened substantially. The scheme also includes a new interchange with the A1 (along with the widening of a short section of A1), and some modifications to the M11 interchange.
M1 J19 Catthorpe 8 March 2017
Reconstruction of M1 Junction 19, the meeting place of the M1, M6 and A14. Provision of new free-flow links between M6 and A14. The plans as of Autumn 2003 will cause the realignment of the road between Catthorpe and Swinford away from the interchange, which in turn will mean the A14 from this interchange to Junction 1 will be upgraded to motorway.
The junction will carry the mainline of the M6 on to the A14, with sliproads between M1 south and M6, and between M1 north and A14.
A14 Kettering Bypass Widening 18 July 2015
M1 J19 Catthorpe Viaduct Replacement 29 September 2014
A scheme to replace the bridge carrying the southbound M6 over the M1. This whole junction is due to be remodelled to solve its endemic congestion problems, but has been further delayed by a government spending review. As a result it was decided that replacement of this bridge could not be put off any longer and will go ahead anyway. The existing bridge has been supported by temporary props in the southbound carriageway of the M1 for some years now.
A14 Copdock Interchange and Dock Spur Roundabout Improvements 21 December 2011
The aims of this scheme are to increase capacity and improve safety at two junctions on the A14 in Suffolk - J55 (Copdock Interchange, A14/A12), near Ipswich, and J60 (Dock Spur Roundabout, A14/A154), at Felixstowe.
At the Copdock Interchange, where congestion is the major problem, additional lanes will provided on parts of the roundabout and on some of the approach roads. In addition, the roundabout will be fully signalised.
A14 Haughley Bends Realignment 11 February 2009
A14 J7 Improvement 26 October 2008
Originally a scheme to grade separate the A14 dual carriageway between Kettering and Huntingdon, closing central reservation gaps and providing new split-level junctions and flyovers.
It now appears that this scheme has been shelved, and the only improvement still on the cards is to A14 J7, the A43 at Kettering, which is having bridges replaced and sliproads lengthened.
