OpenWeb's current imagery is from late January, so current road construction statuses should be taken with a grain of salt as time goes on (however, if I'm recognizing OpenWeb's imagery update pattern correctly, new late May/early June imagery should be available very soon). Sentinel-2 satellite imagery (https://apps.sentinel-hub.com/eo-browser), albeit very low-res, shows this section has been since paved over.

As for the track roads, if they've been graded over, the road that was originally there no longer exists. In the real world, you would need to trespass into a construction site and possible traverse a steep incline onto a new road foundation (which would physically remove an intersection) to travel along these roads. And since the under-construction roads, when built, will most definitely have curbs, possibly sidewalks and landscaping along the side, physical access is further removed and so is the trace of the old road, and it would be unnecessary to intersect the under-construction roads with these sort of informal dirt roads.
