Motorists in and around Luton faced disruption this morning after a serious collision on the southbound M1 left at least one lane closed and sparked a substantial oil spillage. The incident, which took place at about 8.45pm yesterday, involved multiple vehicles and an HGV which came to rest on its side between J11 and J11A.
Immediate impact and response
Emergency services, including Bedfordshire Police and other agencies, attended the scene. National Highways confirmed the overturning of the HGV and reported significant damage to the nearside barrier and boundary fencing. Most lanes were affected by oil on the carriageway, requiring specialist clearance and resurfacing work.
"One of the HGVs involved has overturned and come to rest on its side. There is also significant damage to the nearside barrier and boundary fencing, along with a substantial oil spillage across most lanes."
Current situation and travel advice
By this morning a single lane remained closed southbound between Junctions 11A and 11, with traffic continuing to move slowly past the scene. National Highways reported that traffic which had been held within the closure was released via lane 4. Diversion routes were put in place overnight and work to make the carriageway safe has continued into the following day.
- Location: M1 southbound between J11 (Luton) and J11A
- Time of collision: ~8.45pm (previous evening)
- Current status: One lane closed; oil spillage and barrier damage being addressed
- Nearby facility: London Luton Airport reported to be operating as normal
Local consequences
The closure is only a few miles from London Luton Airport, potentially affecting passengers and staff travelling to and from the airport during peak hours. Commuters using the M1 to reach Luton town centre or surrounding areas should expect delays and check traffic updates before travelling. National Highways has indicated that resurfacing is required in the damaged section, which may prolong lane restrictions until repair work is completed.
