A tractor driver remains in a serious but stable condition after plunging from an overbridge onto the M20’s central reservation.
The accident happened on the A227 overbridge near Wrotham, Kent, at around 11:15 BST on Monday (18 August).
The tractor driver, who was seriously injured, was airlifted to King’s College Hospital in London.
The crash forced the closure of the M20 in both directions, with the stretch between junction three, near Addington, and junction one, near Swanley, closed until just after 23:30.
Kent Police reported on Tuesday morning that the driver is in a critical but stable condition.
