M6 overnight closures j16 to j20

Tonight (Sunday evening) I was getting the J14 - J16 CLOSED warning on the gantry going northbound and J13 - J14 CONGESTION as I was towards the top of the M5 and thought “■■■■ that. Last time I drove into that it cost me nearly 90 minutes” so I detoured through Whitchurch which cost about half an hour on the normal time taken.

Just wondering if anyone drove through it between 2130 and 2300 and can tell me how long they lost and if what I did was worth the effort for future reference (aware that on a Sunday evening it might not be the most representative time to gauge it).
