Drivers will once again have to prepare to find alternative routes with the A14 to be subject to another round of overnight closures.
The extent of the disruption in the build-up to the Christmas period has been announced by the Highways Agency as the work enters its final few months.
Overnight from 8pm on Monday until 6am on Wednesday, the eastbound carriageway will be completely closed between Junctions 7 and 9.
A westbound lane will also be shut at those times.
There will also be a three-night closure of one eastbound lane between the following Wednesday night – December 10 – and Saturday morning, December 13.
One westbound lane will be closed on the nights of Monday, December 15, and Tuesday, December 16, and the whole carriageway will be shut the following two nights. One lane of the westbound carriageway will again be closed on Friday night, December 19.
Finally, in the New Year, there will be a full closure of the westbound carriageway between the two junctions from Friday, January 16, until Monday, January 19.
All the closures are subject to change.
Highways Agency project manager Mary Chatfield said: “People should allow extra time for their journeys and, when there is a full closure in place, familiarise themselves with the diversion before setting off.”
The building of an extra lane in each direction on the heavily congested stretch of road is due to last until the spring.
