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.

The diagrams show measurements of two tunnels in different Australian cities,

along with

the years of construction and cost.

Overall

, the second

tunnel

was built more recently, with the project costing more

due to

its extended length and width when compared to the

first

tunnel

.

However

, the

first

tunnel

went down deeper than the

first

and took longer to construct. Starting with the

first

tunnel

, the

tunnel

was built under a bridge crossing a river, surrounded by sand. It was built between 1986 to 1998 with a cost of $555 million. The

tunnel

itself consists of 2 car lanes, stretching out for 2.2 kilometres and going 1.5 meters down into the ground. Moving on to the second

tunnel

, it was constructed between 2002 to 2006, taking significantly less time than the

first

tunnel

. The

tunnel

is situated underneath a road in the city, surrounded by mostly stone and clay. The price for

this

tunnel

is $1.1 billion, which provided us with 3.6 km of

tunnel

length and 3 lanes for vehicles. Compared to the

first

tunnel

,

this

one remains relatively flat,

instead

of curving downwards like the

first

one.
