Cross Harbour Tunnel
The most impressive events in the latest science and technology is the completion of the Cross Harbour Tunnel. I think that the Cross Harbour Tunnel is a great exemplification of technical and scientific progress of mankind. We all know that there are many problems if you want to get across, needless to say getting a road through the sea to make people travel conveniently. It is difficult to finish this task. So I think it is a miracle of the modern science and technology. Straits, as a natural moat between the continents, makes people's living and travelling very inconvenienct. So people have designed and constructed the Cross Harbour Tunnel. Tunnel is a kind of Harbour Building which is built under the seabed in order to solve the traffic problems between the strait and the gulf 【在海峡和海湾之间?】on the conditions that there is no prejudice to waterage. It also links to the main financial and commercial districts.Tunnel doesn’t occupy space, interfere with the navigation, nor affect the ecological environment, so it is a very safe and all-day strait channel.
