@Corjan-Meijerink IMO changing the oppacity does not really help. I have set it to 80%, but if the scale is 1 km, I still don't see the blocked road:
Only when scale to 300 m, I see the black lines:
I really would appreciate if MRA shows blocked roads with a bold red-white or other clearly visible color scheme. Black near black does not make any sense IMO.
