A 20-mile stretch of the A14 will be closed while urgent roadworks are carried out. 

National Highways, which maintains the country's road network, announced its plans for the roadworks last year. 

Throughout the year engineers have been carrying out works to repair the roads surface and extend its lifetime. 

National Highways has announced plans to move to the next phase of work where they will begin reconstructing lane two of the westbound carriageway. 

To do this they will have to move the barriers which separate the traffic and laying new road markings to ensure the new temporary road lanes and layout are clear and easy for drivers to follow. 

The contraflow system will be moved onto the eastbound carriageway between junctions 47a and 49 overnight on Monday, October 23.

The contraflow system will be fully installed by 6am on Tuesday, October 24, and will remain in place for the duration of the scheme.

For this to happen the A14 will have to be closed overnight between junction 43 and 51, when there is less traffic. 

The eastbound carriageway will be closed between 8pm and 6am on Friday, October 20 and the westbound carriageway will be closed between the same times on Monday, October 23. 

The temporary 50mph speed limit will also remain in place.
