This scheme provides a fourth lane in each direction between the M11 and the A13.
This scheme was completed in and we're no longer accepting updates or changes to this page.
Trees and bushes have started to be removed from embankments between junctions 27 and 28. All set for proper construction to start in July 2009.
A contraflow and 50 limit have now been imposed between junctions 27 and 28. Work is now rapidly advancing on the eastbound carriageway, with the original hard shoulder and land to the side of the road now cleared.
From J27 up to a mile before J28 the works are completed and 4 lanes are now open. The works have now shifted down from J28 to J29.
Work to widen the section between J29-30 is scheduled to start in June 2011.
The section between J28-29 is now fully open.
The main phase of construction is now complete, and the temporary 50mph speed restriction is expected to be removed in the next few days.
The 50mph speed restriction was removed on 23 May 2012. Overnight lane closures will continue until work in the central reserve is completed.
