Planned barrier works up to the 27th it says. Are you heading back North or coming from the North? You could always come off at J30 if heading South on the M61, onto the M60, then M62 and back on at 21a.
I do J26 to J21 everyday and at no point is there any signs or notices for any night closures. But it does list them on the HA website and local press. Maybe it’s just a few lanes out for the barriers?
Well it was fine on the journey down roadworks wise. a crash at staford cost me as did on further south. the return journey was the stuff you can only dream of. 9 and a half hours from Plymouth to Aberdeen
