This picture is the cross-section of a downtown Sydney street. George Street must've been in need of some TLC and the whole thing has been dug up and remade. So I did a bit of looking...
The City of Sydney website explains:
George Street will undergo one of the biggest transformations ever seen in Sydney when the light rail line is built. The City of Sydney has committed $220 million to the public domain elements of the project and is working closely with the NSW Government to create inviting public spaces where people want to live, shop, visit and do business. The main George Street strip will be pedestrianised between Hunter and Bathurst streets and footpaths will be widened. Existing driveway access for buildings will be maintained while roads travelling east and west will remain open to vehicles. Delivery vehicles and taxis servicing the Hilton will travel along George Street as normal. Greater space for pedestrians along the street will mean cafés and restaurants can introduce outdoor dining areas. The revamped George Street will become an easy way to travel between key attractions from The Rocks and Circular Quay to the city centre's retail heart and down to Chinatown. Light rail will also link hotels to the renewed Sydney Convention and Exhibition Centre when it's completedI was there for the Planning Institute of Australia Congress 2017, and kept passing this work on my way to conference. Such high quality and so detailed. I did wonder where the water pipes and wastewater pipes were - of course - as you do.
You can see it's made of reinforced concrete. Various layers.
You can see the light rail tracks on top.
And you can see the provision for signalling, cables, and conduits for Africa. Nobody talked about this stuff at conference, but this infrastructure work has an appearance of durability and quality about it that I've not seen anywhere in New Zealand.
But I'm happy to be corrected.
here. Interestingly, the area in the image looks a bit like how Auckland's QEII Square could have looked had the extra space not been sold off.
