As you can see, no such route exists today. To be precise, such a route does exist, but it is unpleasant, dangerous and not fun to cycle.
The area is built up and you are left pining for such quality infrastructure as the St Philip's flyover, visible in the distance.
It is certainly a relief to get off this unpleasant and dangerous path and into the safe cycle facilities around Templemeads.
Victory to Oceania!
