Looking at the segments requested to be unlocked, it seems they are already L1, unless I am misreading something.
The current SL also look a little off, with 80k in one direction and 50k in the other, and the northern segment of the 2, having SL in one direction only.
Please have a close look at this and update with your local knowledge.
You are right about the level 1 - I was just so rusty at WME I wasn’t making the temporary roads correctly to split the segments at the speed limit signs. Done now.
As for the SL being different in either direction - unfortunately I can assure you that is actually the case as it is directly in front of my house! My neighbour has tried multiple times to get the council to rationalise it to 50kmh both ways (we have heaps of ‘roos and they get hit by cars heading north around the bend at 80kmh.)
