The diagrams below give information about two road tunnels in two Australian cities.
Summarize the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.

Sample 1:

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

Overall, there are a number of differences between the two tunnel systems, 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 for 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 2.2km long, and the second tunnel being 2.5m high and 3.6 km long. The first tunnel system is four lanes wide, while the second tunnel system is six lanes wide.

Sample 2:

The diagrams compare the design of two underground tunnels in Australia. Overall, it can be seen that the more recently built tunnel, which facilitates urban traffic, displays more advanced features at twice the cost of the older, river-spanning one.

The first tunnel was constructed from 1986 to 1988, costing 555 million dollars. It stretches from one end to the other of a bridge over a river, covering a distance of 2.2 kilometers. In addition, this tunnel, which could accommodate four lanes of vehicle traffic, went 1.5 meters underneath a surface of sand.

Meanwhile, construction of the second tunnel began in 2002, and it was not until 2006 that the route was opened for traffic. With a price tag of 1.1 billion dollars, this tunnel has a span of 3.6 kilometers and lies beneath an overground motorway. Besides being longer than the former tunnel, it provides more space for vehicles as well, at 6 lanes. The more modern building technology is further reflected in the fact that this route went 2.5 meters deep in terrain composed of clay and stone.

Sample 3:

The diagrams illustrate information regarding the structural and financial specifics of two road tunnels situated beneath Australian cities.

Overall, it is apparent that both tunnels were constructed to facilitate vehicular movement, with the latter surpassing the former in terms of length, depth, and financial investment. Moreover, the foundational composition of each differs markedly.

The tunnel completed in the time frame from 1986 to 1998 measures a length of 2.2 kilometers and is embedded 1.5 meters under a layer of sand. The cost incurred for its construction stood at $555 million which accommodates a bi-directional flow of traffic across two lanes on each side of the tunnels. In comparison, the second tunnel, which was built between 2002 and 2006, extends for 3.6 kilometers and delves to a depth of 2.5 meters into a substructure of stone and clay. This larger scale of construction was reflected in its cost, which reached a substantial $1.1 billion. The design, similar to the first, provides two tunnels but has one more lane compared to the one built earlier.

Sample 4:

The diagrams show the distinctions between two tunnels in two cities in Australia. Overall, the newer tunnel is superior to its older counterpart regarding its length, height, and traffic capacity. Additionally, although the older tunnel took much longer to construct, it is about half the cost of the newer one.

Regarding the construction duration, traffic volume, and price of the two tunnels, the first tunnel, initiated in 1986 and completed in 1998 (twelve years of construction), can accommodate two vehicles simultaneously in each lane. However, the second one's construction necessitates significantly less time, taking place between 2002 and 2006, but it allows for the movement of three vehicles at a time. Furthermore, $1.1 million was allocated for the construction of the new tunnel, compared to only $555 million for the old one.

Concerning the height, length, and location of the two tunnels, the first one is 1.5 meters high and 2.2 kilometers long; at the same time, it is positioned under a bridge spanning a water body as well as separated from the water and bridge by a layer of sand. The second one, longer and taller at 3.6 kilometers and 2.5 meters, respectively, is built under a highway, with a layer of stone and clay separating the tunnel and the highway.
