The maps compares two underground tunnel for cars in two different cities in Australia

Overall, tunnel under the road went deeper, more costly, which was the main road, and wider than tunnel under the river. Moreover, tunnel underground below the road covered by stone and clay, whilst the others protected by sand.

Tunnel under the road built 2,5 meters under the surface, and it covered by stone and clay. It built from 2002 to 2006 and cost more than 1 billion dollar. Furthermore, that tunnel can filled by 3 lines of car on both sides and had the length at 3,6 kilometers.

In the other city, tunnel built under the river. It took around 12 years to built and cost at $ 555. That tunnel covered by sand and the position were 1,5 meter below and the length is about 2,2 kilometers. Meanwhile, in the outside of those tunnels, was a river and the bridge above them. in addition, it appears that those tunnel only had a 2 lines of cars on both sides.

The given maps illustrate two different underground tunnel system for cars in two Australian cities.

Overall, there are a number of differences between the two tunnel system, in terms of the cost, size, length, time of construction, and the surrounding environment. The first tunnel cost approximately half as much as the second tunnel to construct, however, the first tunnel was significantly smaller in terms of length and vehicle capacity. The first tunnel also took much longer to construct.

The first tunnel, which took twelve years to construct between 1986 and 1998, cost $ 555 million, and was built underneath a body of water and sand. Meanwhile, the second tunnel only took four years of completion but cost twice as much, at $1,1 billion, and was constructed beneath a layer of stone and clay.

The size of the tunnels was also substantially different, with the first tunnel being 1,5 meters high and 2,2 km long, and the second tunnel being 2,5 meters high and 3,6 km long. The first tunnel system is four lanes wide, while the second tunnel system is six lanes wide.
