Upcoming road closures in March 2024
Work began on Monday 6 March 2023 and is expected to be complete by Friday 22 March 2024.
Upcoming closures and diversions
Our final phase of work will take place between Thursday 14 and Friday 22 March. We’ll be working overnight between 8pm and 6am, as follows:

Whist the A11 is closed, traffic will be diverted as follows:

Upcoming road closures in February 2024
Our next phase of work will take place on the A11 southbound between Six Mile Bottom and Balsham Road from Monday 5 February to Thursday 22 February. Work will be done on weeknights between 8pm and 6am.
To do the work safely, we need to close the A11 southbound, and traffic will be diverted via the A14 and M11 (using the strategic traffic diversion).
Strategic Diversion
Any traffic wishing to join the A11 southbound at Six Mile Bottom will be diverted. Traffic will follow Wilbraham Road and the A1303 to join the A14 westbound at junction 35 (Stow cum Quy), then follow the strategic traffic diversion.
A11 Entry slip diversion
The A11 northbound exit slip road at Six Mile Bottom will also be closed. Drivers will be directed to continue on the A11 / A14 Newmarket Bypass and exit onto the A1304 (High Street) through Newmarket to return to Six Mile Bottom.
A11 Northbound Six Mile Bottom diversion
Other planned work
We also plan to carry out maintenance and improvement work on the A14 between Cambridge and Newmarket.
This work will include resurfacing, replacement of road markings, signs and road studs between junction 35 (Stow Cum Quy) and junction 36 (Nine Mile Hill). This will ensure the A14 remains safe and serviceable for years to come.
The work will take around 6 months, starting on Monday 19 February 2024. We’ll be working mainly on weeknights with some weekends, between 8 pm and 5am or 6am, weather permitting.
The first phase will need road closures on the A14 eastbound, and will so not affect the diversion for when the A11 southbound is closed.
