The basic matetrials were steel and concrete.

Great Britain and France are connected by the Eurotunnel. It's a 50km tunnel underwater that is commonly called the chunnel. It was opened in 1994 after construction began in 1988.

It depends on the bridge, becaue you have to take into consideration the length, the material, and the location.

some materials used in bridges are concrete, steal, metal [may rust and fall if metal ]

the first bridge may or may not have been made of wood

The Iron Bridge crosses the River Severn at the Ironbridge Gorge, by the village of Ironbridge, in Shropshire, England. It was the first arch bridge in the world to be made out of cast iron, a material which was previously far too expensive to use for large structures. However, a new blast furnace nearby lowered the cost and so encouraged local engineers and architects to solve a long-standing problem of a crossing over the river.

When I did History in High school, I think it was 8th grade, we did british history and we learnt that the tower of London was built by William the conquer, as his home, It was named because it was situated in London, and it was a large castle with a tower.

While more than 200 people have died falling or jumping off the Humber Bridge, no one seems to have died during the construction process.

Eurotunnel is the name of the company which owns and operates the Channel Tunnel, as well as other business interests.

Pedantically, a tunnel cannot move and cannot have a speed!

The maximum speed allowed in the Channel Tunnel is 160 km/Hr.

A train takes approximately 25 minutes to go through the Channel Tunnel.

Eurostar is the brand name of the company running high speed trains London-Paris and London-Lille-Brussels through the Channel Tunnel.

Eurostar trains run at up to 300 Km/Hr on the High Speed Lines on either side of the Channel Tunnel.

The Eurostar takes 2 hours 15 minutes between London and Paris. There is approximately one train per hour in each direction.

• The construction of the golden gate bridge started in January,5 1933 took 4 years then finished in April, 19 1937.
• The construction of the Bay bridge began in 1936 and opened November 12, 1936.

It depends on what your making out of. I only know about wooden models for metal, etc you'll have to ask someone else. But if your making it out of wood then you need to give it a lot of trusses, beams, archs and make sure it has pivots.

this is my first answer !

The traditional (and original) color of the bridge was black. Now, for some reason, it is an ugly shade of blue.

The Tees Viaduct, opened in 1975, is a famous British bridge. Others include the Albert Bridge, the Alloa Swing Bridge, and the Tower Bridge in London.

Ten Miles long and 200 feet at the highest point of the Bridge.

To help rest of people get to the other side

Suspension bridges are great for long distances and can span up too 7000 ft.! It s great for Long distances and its light weight. But its terrible under high winds . its very very flexible

Although many people think that there was a bridge for that purpose, I doubt there is. If their was a bridge they would have been destroyed and sunken into the ocean. If there is to be one then it would have to go deep into the north pole and back into the Americas.

30 -35 minutes inside the tunnel.
