basically both carriageways are closed between J3-J4 on the M27 (J4 is also where M27 connects to M3)
This would definitely be worth adding asap 
Hi Tim, welcome to the forum. Thanks for letting us know about these closures. Evenso, these closures should be picked up by the ClosureMonitor, so we don’t need to add closures manually.
Ooh that’s a nice bit of scripting work!
That’ll hopefully make my Saturday morning travel easy
Thanks for the response
