The Slacks Creek Corridor is nice though, and there are works due to finish soon that will see nice wide paths put along the pacific hwy (western service road) all the way from paradise road (past park road where the SCC comes out) all the way to its end near the logan road/compton road intersection. There is then a path to that intersection and nice crossings there now. So you can go diagonally across and onto Bernice Ave, and then up to underwood road in the quiet streets between logan road (95) and the motorway (with just a tricky crossing at springwood road)

Thanks for the detailed answer! Yeah I assume the problem is due to the V1 ending at the boundary between the cities of Brisbane and Logan. When you are driving you don't really notice a divide, but for active transport there seems to be a no-mans land less traversable than the Somme.. I think my problem is I have a road bike (so can't ride on anything but paved) but don't have the confidence of your usual road bike user. I'm looking into getting a hybrid ebike, so maybe those grassy verges around the begining of the V1 wouldn't be so bad then!
