Rozelle Interchange opened today - it’s an underground motorway interchange with three levels and several connections to the surface, just outside the CBD of a city of 5m people…

Its scale is truly massive - 16km of road tunnels, $4Bn, 4.5 years to build. I worked on the design development and it’s nowhere near as complicated to follow as the headlines suggest, but that’s not good for headlines!

PS Rozelle looks epic from a bloke/boy/girl/nerd/geek point of view
It is - I was part of the design development team for three years - learned lots!

As for the total time - 4.5 years was just the construction period. Planning and development for started about 10 years earlier. In fact, the whole general scheme, of which Rozelle is part, was conceived in the 1940s, so not really that quick…biggrin
