Our final phase of work will take place on the A11 southbound between Granta Park and Stumps Cross from Thursday 30 November 2023 to Wednesday 24 January 2024. Work will be carried out on weeknights between 8pm and 6am.

We will not be working between Thursday 21 December 2023 and Friday 5 January 2024 as our policy is not to have planned roadworks during the festive season.

Closures and diversions

To carry out the work safely, we need to close the A11 between Granta park and Stumps Cross, one direction at a time.

While the A11 is closed, traffic will be diverted to exit the A11 at the merge point with the A505, then take the A505 westbound to reach junction 10 of the M11, then follow the M11 southbound.

M11 junction 10 slip road resurfacing

Separate to the A11 work, we will also be carrying out resurfacing on the M11 junction 10 southbound exit slip road (leading to the A505 and Duxford Imperial War Museum).

To carry out this work safely, we will need to close the M11 overnight as follows:
- M11 southbound between junctions 11 (Trumpington) and 10 (Duxford), Tuesday 28 November, between 10pm and 5am.
- M11 junction 10 southbound exit slip road, from Wednesday 29 November to Friday 1 December, between 10pm and 5am.
During these closures, southbound traffic will be directed to exit the M11 at junction 11 (Trumpington), take the A10 southwest to Royston, then the A505 to rejoin the M11 at junction 10.

Project information

We are resurfacing the A11 between Babraham, where it joins the M11 and Six Mile Bottom, where it joins the A14. We will also replace the central reservation safety barrier and signage.

Drivers will benefit from safer and smoother journeys as we resurface the A11 and replace road signage.

Drivers heading northbound will follow the M11 north and then the A14 east to rejoin the A11 near Newmarket.

There will be local diversion routes in place when the A11 is closed in different stages.

Local diversions

Monday 6 March to Tuesday 2 May - A11 southbound from Worsted Lodge to Fourwentways.

Drivers will exit the A11 at Fleam Dyke, taking Cambridge Road west to pass through Fulbourn and then turn left onto Limekin Road. Another left turn will return drivers east on the A1307 Babraham Road to rejoin the A11 at Fourwentways.

Tuesday 2 May to Friday 11 August - A11 northbound from Fourwentways to Six Mile Bottom

Drivers will exit the A11 at Fourwentways to head west towards Cambridge on the A1307 Babraham Road. They will turn right to head north on Limekin Road and then right again to return east on Cambridge Road to pass through Fulbourn and rejoin the A11 northbound at Fleam Dyke.

Friday 11 August to Wednesday 11 October - A11 northbound from Six Mile Bottom to Nine Mile Hill

Drivers will exit the A11 at Six Mile Bottom, taking the A1304 towards Newmarket. They will turn left at the roundabout to head west on the A1303, then join the A14 eastbound at junction 35 (Stow cum Quy) to resume their journey north on the A14/A11.

Wednesday 11 October to Thursday 23 November - A11 southbound from Six Mile Bottom to Balsham Road

Drivers will follow the strategic diversion.

Thursday 23 November to Friday 2 February 2024 - A11 southbound from Granta Park to Stumps Cross

During the first week of work, drivers heading southbound will exit onto the A1307 at Fourwentways, then turn off towards the services to take Newmarket Road south running parallel to the A11, then at Granta Park either go straight over the roundabout to return to the A11 south or turn right onto the A505 to join the M11 at junction 10.

During the rest of this phase drivers will exit the A11 southbound onto the A505 westbound, following it to Duxford to join the M11 at junction 10 and continue south.
