Drivers in Northamptonshire are being warned to avoid the A4500 Weedon Road from Kislingbury towards the M1 as police work to remove a lorry toppled on its side.
The incident occurred at the roundabout off junction 16 of the motorway shortly after noon.
PC Dave Lee, of Northamptonshire’s Roads Policing Unit, said both the driver of the juggernaut and another car involved in the incident suffered only minor injuries.
The officer tweeted via the account @NorthantsPolice_RPU: “If you are leaving Northampton heading north on the M1 or to Daventry, please join the M1 at Jct 15a and exit at jct 16. The A4500 is closed.”
Police say the road will likely be open again at 4pm.
