The steel casing that uses random steel beams forms the outer covering whereas there is the sitting area build in concrete on the inside. Each beam weighs around a thousand tons and all the steel required was manufactured in China itself . Today it has a siting capacity of more than 80000 people. The stadium has a rain water collecting system which is then on purification used for the stadium . The ground pipes do the work of keeping up with the temperature around providing heat in winter and cold in summer. The entire structure costs around 230 million American dollars.

Out of the 50.5 km ; 37.9 km is under the sea with 290 feet deep in the deepest area. Building a tunnel as it is a difficult task but building it under a sea is a mighty task. The high speed Euro star runs in the tunnel and also the Euro shuttle vehicle transport service. The tunnel cost 4650 million which was 80% more than predicted. The construction began in 1988 and finished in 1994. Workers from both the country were involved. The tunnel supports 2 rail routes and 1 service route.
