There's a path on the east side of Nicholson onto the Roe Hwy path but not on the west side. I got caught out the first time I rode that way.
Yeah I wasn't going to cross Nicholson, would be easier to just go round the other side of Whaleback golf course, but High Rd was actually OK out there.
Roundabout at Nicholson/Garden/Yale is a bit crap too, pushes you onto the footpath, then dumps you back at the road trying to force you to go across, so back onto the road anyway. Probably just stay on the road next time.
The roundabout is designed for cars, not cyclists. Due to the slip lanes, if you want to cross diagonally from the path on Garden St to the path on the north side (east of Nicholson), I think you have to cross something like five roads.
Even crossing just Nicholson on the north side is four road crossings if you are on the path. If you are on the road, you might as well just throw yourself under a truck.
