Bridges and Tunnels

A bridge in Minneapolis, Minnesota. But I don't know the name.

The Great Belt Bridges are located in Denmark.

The Ironbridge at Coalbrookdale in Shropshire, England, completed in 1779, was the first major structure to be constructed entirely of iron.

The first major structure built entirely of steel was the cantilevered Forth Bridge in Scotland, completed in 1890.

From the road section:

8.6 metres (28ft - closed)

42.5 meters (139ft - open)

The firm Dorman, Long and Co built the Tyne Bridge from the designs of the engineering firm Mott, Hay and Anderson.

It depends what kind of, and what style of bridges you want. Here is a few things I have seen used that you could use for model and usable bridges.

concrete

the total length of Millau viaduct bridge is 2460 mtrs or 1.53 mill. this is the world tallest' bridge that linking Paris to mediterranean.

The average length of a beam bridge is 40 meters to 500 meters. So it can only go up to 500 meters.

The likelihood of a dog walking across a bridge causing it to collapse is extremely low. Bridges are designed and built to withstand much heavier loads than the weight of a single dog. Factors such as the bridge's structural integrity, design, materials used, and maintenance are far more significant in determining its safety. It would take a highly unusual set of circumstances for a dog to cause a bridge to collapse just by walking across it.

No, they are not the same bridge. Three bridges connect Lower Manhattan to Brooklyn: the Brooklyn Bridge, Manhattan Bridge and Williamsburg Bridge.

The Brooklyn Bridge is the furthest south, the Manhattan Bridge is in the middle, and the Williamsburg Bridge is the furthest north.

The Brooklyn Bridge was originally called the "New York and Brooklyn Bridge," which is perhaps where some of the confusion comes from. But when the bridge opened in 1883, New York City consisted mostly of just Manhattan. It was not until 15 years later, in 1898, that the five boroughs -- Manhattan, Brooklyn, Queens, The Bronx and Staten Island -- united to form modern-day New York City.

Before then, Brooklyn was its own city (the other three consisted of small towns and farmland), so the bridge was called the "New York and Brooklyn Bridge" because it united the city of New York and the city of Brooklyn.

Of course, today Brooklyn is part of New York City, so calling it the "New York and Brooklyn Bridge" is redundant.

You cannot "invent" a tunnel.

You can plan it, and construct it. Both these activities involved thousands of workers.

There have been many proposals to build a Channel Tunnel. The two governments (France and the UK) held a competition for the best proposal, and then a company was set up to build it. The successor to that company (called "Eurotunnel") now owns and operates the tunnel.

You cannot say that one person invented the Channel Tunnel.

Stourbridge, Corbridge, Cambridge, Hebden Bridge, Axbridge and there are probably many more as towns were very often built near a bridge over a river and named after the bridge. Cambridge is a very good example of this - named after the River Cam.

When a vehicle runs on the bridge, the centrifugal force experienced by the vehicle owing to its rotational motion acts outwards and reduces the inward force because of the weight of the vehicle thus reducing pressure exerted on the bridge because of the vehicle. This makes the bridge lasting,

well since its a bascule bridge you can use mini motors.

connect the mini motors to a string and attach it so you can pull the leaf.

The rainbow bridge is a natural rock formation that can be found in San Juan County, Utah. It is a protected national monument, once used as sacred Indian grounds and should be approached in a respectful manner.

Disadvantage: An arch bridge requires a very stable foundation. The bridge diverts the

tension exerted on it onto the foundations on either side of the bridge.

Advantage: It is an economical way to traverse small distances and is able to cope with

bending forces

it just is ok

No. It can be one of the worst places; although there is video footage of a man with his daughter surviving as they took cover under a bridge. They survived mainly because the tornado missed the bridge. The bridge itself creates a wind tunnel effect that cause the wind to accelerate as it passes through. Additionally, bridges offer no protection from debris, which is the main killer in a tornado.

The purpose of a suspension bridge is to carry traffic across a body of water without the use of too many legs. Let's say two cities are separated by a river. Naturally, the governments would want to build a bridge over the water, to connect the two cities more easily.

Then they realize that under the river, the terrain is very rough and deep. Instead of spending billions of dollars on leveling the terrain to accommodate the bridge legs, they decide to build one main vertical support on each side of the river. They have vertical cables (held by horizontal cables strung between the towers) supporting the bridge where there are no legs, thus eliminating the need for legs or the risk of bad support in the center of the bridge, already being the weakest.

As far as my research shows there are 101 bridges across the thames
There are over 100 bridges that cross the river Thames and they have all been listed elsewhere on this site.
27 within London and about 200 along its entire length.
