Construction of a new underpass linking the A13 dual carriageway from London to the A130, allowing traffic to flow more easily between the A13, A127 and A130 dual carriageways avoiding the current interchange at Sadlers Farm. The "magic roundabout" will be rebuilt into a standard signalised as part of the works.
A short new link connects the A13 directly to Canvey Island.
This scheme was completed in and we're no longer accepting updates or changes to this page.
Work is starting this month on the new underpass.
Construction started on 12 July 2010. The work is due to be completed by March 2012, in time for the Olympic mountain biking event at Hadleigh.
Old A13 (London Road) has been diverted to allow the construction of the bridge over the new link. You can see the line of the new link as you drive along it.
The scheme is on schedule to open to traffic on 31 May 2012, although some finishing work will continue until the end of June.
