M1 reopens near Chesterfield as shocking pictures reveal extent of lorry crash
All lanes on the M1 have been reopened after they were closed this morning due to a crash involving two lorries which swerved to avoid a roof box.
Derbyshire Roads Police said the roof box was flying through the air after it had been blown off a car by the wind.
The incident took place between J29 and J29A near Chesterfield on the northbound side of the M1.
The closure of two lanes caused tailbacks to J28 and half-hour delays.
