Essay topics:

The maps below depict two different subterranean tunnel systems in two Australian cities.

The given two pictures illustrate the two distinct underground tunnel systems of two cities in Australia.
Overall, it is evident that there are striking differences between the two tunnels in terms of cost, size, time of construction and surrounding environment. The first tunnel costs approximately half as much as the second one; however, it required a longer period of time to construct. The second system, meanwhile, is dominant with regards to length, width and vehicle capacity.
Looking at the information in more detail, the first underground system, which took twelve years from 1986 to 1998 to complete, costs around $555 million and is constructed beneath a body of sand. The second tunnel, in stark contrast, was erected during four years between 2002 and 2006 but required a considerable $1,1 billion. This system is positioned underneath a layer of stone and clay.
As far as the size is concerned, the first tunnel is 1,5m wide and 2,2km long, while the second one’s width and length are 2,5m and 3,6km respectively. Whereas the former is only four lanes wide, the latter is six lanes wide.
