Delays expected as lorry overturns on A1

The A1 northbound in Nottinghamshire is closed between the A57 South (Markham Moor) and A57 North (Apleyhead) due to a collision involving an overturned lorry.
There is also a lane two closure on the southbound carriageway due to extensive central reservation barrier damage.
Emergency services and recovery are on scene. A team is on route to repair the central reservation barrier once recovery is complete.
