Motorists travelling on the M11 northbound in Cambridgeshire are facing an overnight full carriageway closure on Sunday, September 27, 2026, as part of ongoing road reconstruction work.
The affected section runs from Junction 9 at Stump Cross to the A11 Fourwentways Roundabout. Current traffic information lists the closure as planned roadworks rather than a collision or emergency incident.
The restriction is expected to affect motorists travelling north towards Cambridge and the surrounding areas, with drivers advised to allow additional time and follow signed routes.
Why Is the M11 Closed Tonight?
The northbound closure is part of planned carriageway reconstruction and renewal work being carried out on behalf of National Highways.
The affected stretch between Junction 9 and the A11 Fourwentways Roundabout has been scheduled for full overnight closure to allow the work to take place safely.
National Highways’ road-closure information confirms that the M11 is among the roads scheduled for planned full closures in England.
M11 Northbound Closure Times
Current traffic information lists the closure for the night of Sunday, September 27, into Monday, September 28.
There is some variation between traffic-information sources over the precise overnight hours. One current listing gives 9 p.m. to 5 a.m., while another lists 10 p.m. to 6 a.m.
The important point for motorists is that the full northbound carriageway is scheduled to close overnight, so drivers should not rely on being able to use the affected section during the closure period.
Which Part of the M11 Is Affected?
The main restriction covers:
M11 northbound, Junction 9 to the A11 Fourwentways Roundabout.
Junction 9 is the Stump Cross area, while Fourwentways connects with the A11 and provides access toward destinations including Cambridge and Newmarket.
The closure means motorists travelling northbound through this section will need to leave the affected route and follow the appropriate signed diversion.
Is There an M11 Crash Today?
Despite searches for an “M11 crash today,” the currently verified disruption on this section is associated with planned roadworks rather than a confirmed major collision.
Current traffic information identifies the northbound closure as roadworks and gives the reason as carriageway reconstruction.
This distinction is important because social-media posts and search headlines can sometimes describe motorway disruption as an accident before the cause has been confirmed.
At the time of publication, the available information reviewed does not establish a major crash as the reason for tonight’s principal M11 closure.
What Work Is Being Carried Out?
The closure is connected with reconstruction and renewal of the carriageway.
Closing the entire northbound carriageway overnight gives contractors space to carry out work while reducing the risks associated with operating construction equipment alongside live motorway traffic.
The same section was also scheduled for an overnight closure on Saturday, September 26, meaning the current restriction forms part of a wider programme of work rather than a one-off response to a crash.
What Should M11 Drivers Do?
Anyone planning to use the M11 northbound around Junction 9 tonight should check the latest traffic information before leaving.
Drivers should:
- Allow additional time for their journey.
- Avoid the closed section where possible.
- Follow official diversion signs.
- Check live traffic conditions before travelling.
- Be prepared for additional congestion on alternative routes.
Traffic conditions can change quickly, particularly when a major motorway is closed overnight.
Are Other M11 Restrictions in Place?
There are also longer-running works elsewhere on the M11.
Current traffic information lists a southbound hard-shoulder closure around Junction 11 as part of construction activity. That restriction is scheduled to continue for an extended period and is separate from tonight’s full northbound closure between Junction 9 and Fourwentways.
Drivers should therefore distinguish between the temporary full carriageway closure tonight and other ongoing traffic-management measures on the motorway.
