The provided diagrams illustrate the layout of two road tunnels in an Australian city.
Overall, it is obvious that tunnel A was installed earlier and its size is smaller and shorter than tunnel B. Additionally, they both have twin tubes crossing sections of the tunnel.
To be specific, Tunnel A was constructed slightly shorter in depth, with 25 meters width and 2, 2 kilometers long, than Tunnel B with 35 meters width and 3. 5 kilometers long. Furthermore, there is a layer of stone and sand set up to separate the river and the road in Tunnel A, whilst the road was erected across Tunnel B from start to end point.
Started in 1987, it tooks Tunnel A 5 years to be finished, while Tunnel B was introduced shorter than 2 years, from 2004 to 2007. Nonetheless, Tunnel A only needs 55 million dollars to be completed, whereas the total amount of money of Tunnel B is much more roughly a half, at 1, 1 billion dollars. another striking difference is that there are only two lanes of each tube in Tunnel A, yet Tunnel B can hold up to three lanes of each.
