The high bridge has the longest cable-stayed main span in the world for both road and rail traffic. Longest span : 490 m Total length : 7845 m Width : 23.5 m Clearance below : 57 m

Millau Viaduct : World’s tallest bridge

The Millau Viaduct Paris - Barcelona

Under construction is the highest bridge in the world. This bridge will be part of the A75 to link Paris with Barcelona.

This suspension bridge has a total length of 2.5 km and crosses the Tarn

River. It is 343 meters high, a world record. The road, with two lanes on each

side, will cross the river at 270 meters above ground. At its highest point, the

viaduct is even higher than the Eiffel Tower. Conceived by Norman Foster, this

suspension bridge is supported by seven pylons, instead of the two that are

common for this kind of construction.

The total cost of the project is around 310 million euros (AUD $525 million).

It is formally inaugurated in December 2004, just 39 months after work began.

This is the only rotational boat transporter in the world. It has two arms and each arm forms a kind of huge tub filled with water. Boats enter the tub, then the tub locks up and the huge arm starts rotating .

Otáčení...

Just before “landing”

Closing the gate , regulation of level of water and “tubs” rotation Takes 15 min. only.

One “tub” 78ft. Long with water and boat weights about 300 tons.

The “tubs” are filled according the Archimedes’ Law. So the weight of “tubs” are balanced. To open the upper and lower lock and turn the whole system by 180◦ they need an engine of 22.5 kW which only use 1.5 kWh
