Update, 11am: The road has now been reopened.
Drivers are facing delays on the A46 in Lincoln due to an overturned lorry.
One lane is closed following the crash at South Hykeham southbound at the Pennells roundabout.
Police have said vehicles can pass, however the carriageway is down to one lane.
People are being advised to find alternative routes for the time being.
It is expected that the lane will be closed until around 9.30am for recovery of the lorry and to clear a spillage of grain.
