There's still a gate but it's permanently open now and the trail heading NW is part of the new Quarry Hills Connecting Trails Project. I'm not sure whether to just delete this therefore.

There's a path through here from just off Vanbrook (there's a chain) and down an access road to a pedestrian / cycle sized gate at the indicated point, then down that grey bit and around the corner to join the little trails at the bottom. The map seems to have a "Plenty River Trail" label but no actual route?

This section of Happy Hollow Track has been gated and marked as private property for a few years now. I haven't confirmed the actual legal status though.

This path is closed from about this point southbound by the M80 roadworks. It is no longer possible to get through here to Killarney Ridge by foot or cycle.

The path under the Ring Road to Yando St is closed until "late 2026" at least.

This section of trail (between Punkerri Circuit and the pipeline reserve) is closed with locked gates ... I confirmed with Nillumbik Council that this is private property and no longer accessible to cyclists or pedestrians. There's still a trail there but it probably should be marked as "private access" therefore.
