    Emergency overnight road closure on A14 junction 37 to 38 eastbound

    Drivers are being advised of a full overnight closure on the eastbound carriageway A14 tonight near Newmarket as a result of ongoing flooding.

    We have been continually working on the A14 Eastbound between junction 37 (Newmarket) and junction 38 (Red Lodge), due to flooding resulting in a full eastbound road closure.  
    Efforts to clear the flooding are ongoing: at one point overnight there were 11 tankers on the scene working to remove the water.

    However, excessively high ground water levels which are not naturally draining away, combined with the recent heavy rain, have contribute to a challenging situation. 
    Up until this morning (Friday), we estimate we've removed more than 7 million litres of standing water on the road, equivalent to nearly three Olympic-size swimming pools. 

    The Eastbound carriageway on the A14 will be closed tonight (9pm to 5am). This will allow work to further work to reduce the flooding, carrying out investigative work and assessing the condition of the carriageway. 

    We apologise for the inconvenience caused to local communities. We urge drivers to avoid the area, if possible.

    Emergency lane closures on A14 junction 37 at Newmarket, and junction 39 at Kentford.

    Emergency lane closures are currently in place due to flooding on A14. The A14 eastbound between junction 37 near Newmarket, and junction 39 near Kentford is closed except for lane 3.

    The westbound carriageway has one lane closed between junction 37 and junction 38 with sandbags on the road.

    Our team has been at the scene since last week trying to clear the road of flood water.

    We have worked hard to get one land eastbound reopened. With the forecast of more heavy rain coming, we may have to close it again at short notice. We apologise for any inconvenience caused. 

    We are continuing to work with Anglian Water to find the source of the flooding which is also affecting other roads in the area as part of a widespread issue.

    Until these investigations have been done, we are unable to confirm when the road will return to normal.

    We appreciate that this is a very busy stretch of road and we are currently working 24 hours a day to find the problem.

    We advise drivers to plan ahead if they are travelling on the A14, with delays of up to 90 minutes.

    An official diversion has been put in place with drivers told to exit the A14 eastbound at junction 37 and join the A142 into Newmarket.

    At the clock tower, turn left and follow the A1304 to the junction with the B1506.

    At the junction, turn right and follow the B1506 through Kentford to re-join the A14 eastbound at J39 at Kentford.

    Our planned work between junctions 35 and 36 is not affected by the emergency flood work.

Project information


We are doing maintenance work on the A14 between Cambridge junction 35 (Stow Cum Quy) and Newmarket junction 36 (Nine Mile Hill) starting in February 2024.

Previously, during June to November 2023, we repaired the road and improve the safety of the A14 west of Newmarket to Bury St Edmunds, between junctions 36 to 43, as well as bridge work in Newmarket.

Our 2023 work included refreshing the road markings and road studs (cats' eyes) between junction 36 and 43 and resurfacing between junction 42 to 43 at Bury St Edmunds. We also installed new road signs between junction 42 to 43, and dis some essential bridge maintenance work in Newmarket.

This work will ensure the A14 continues to remain in a safe and serviceable condition in these areas.
