    We start work on 3 March

    We're installing new drains on the A14 near Spaldwick and Bythorn in Cambridgeshire. They will disperse surface water more effectively reducing flooding in future.

    We start work on Monday 3 March 2025 for around 12 weeks.

    We'll work overnight between 8pm and 6am on weeknights only, weather permitting.

    Closures and diversions

    To work safely, we'll need road closures in one direction at a time.

    We'll close the A14 between 13 (Thrapston Interchange) and 21 (Brampton) overnight on the following dates:

    Monday 3 March to Wednesday 5 March

    A14 eastbound between junctions 13 and 21.

    Thursday 6, Friday 7 and Monday 10 March

    A14 westbound between junctions 21 and 13. 

    There will also be a temporary 50mph speed restriction during the work.

    Diversion

    If you're travelling westbound you should:

    • take the A1 northbound towards Alconbury
    • continue onto the A1(M) to exit at junction 17
    • take the A605 to Thrapston, before continuing your journey

    If you're travelling eastbound, follow this diversion in the opposite direction.

    We'll need further diversions in April and May. We'll publish details on this page closer to the time

    Please remember that closures can change at short notice. You can check the latest information on our daily closures page or find live travel information on our Traffic England. Our travel alerts give details of live incidents on our network.
