Great start Mal.
I had always planned to do a similar job route by route rather than all in one hit.

There is a single crossover between the Sir Robert Risson Terminus scissors and Collins St.
AFAIK there is a crossover in Kingsway, within this field of view.

There is a crossover in Swanston St north of La Trobe St.
AFAIK there is also one in Swanston St between Flinders St station and Yarra River.

Docklands really needs two versions post 1980, since one major addition has now been a major subtraction.
