What is the shortest street in the world?
According to the first Related Link (see below), Edgar Street is the shortest, at 63 feet (19 meters). However, according to the measurements I got from Google Maps, Edgar Street is actually 131.25 feet (40 meters) long. Edgar Street is located in the Financial District. Its one-block span runs between Greenwich Street and Trinity Place, one block south of Rector Street.
According to the New York Times (see the second Related Link) Mill Lane is the shortest. Oddly enough, the writer of the Times article apparently did not think it necessary to provide the length of Mill Lane, but, according to the measurements I got from Google Maps, it is just a hair's breadth shorter than 100 feet (30.5 meters) in length.
So, at this time, Mill Lane seems the most likely contender for the title of Shortest New York City Street. Mill Lane is also located in the Financial District. Its one-block span runs between South William Street and the eastern stretch of Stone Street (a tiny street that is actually two streets, as its path is broken), one block south of Hanover Square.
The world's first cast iron bridge was built over the River Severn at Coalbrookdale in the year 1779.
What material was used in early suspension bridges?
The societies that lived in South America, Africa and Asia thousands of years ago strung twisted vines attached to trees to cross over rivers. They added branches to create a flat surface to walk upon.

What is the oldest bridge in New York?
According to Wikipedia, the oldest bridge in New York State is the Hyde Hall Covered Bridge (1823). It's also recognized as the oldest covered bridge in the USA, although some folks in Vermont might contest that.

Why is the Sydney harbour bridge called Sydney harbour bridge?
Arch bridges are one of the world's most ancient bridge forms. The arch gives the bridge its essential strength. Between the engineer of the Sydney Harbour bridge, Ralph Freeman, and the designer, JCC Bradfield, this was seen as the best option for the purpose.
Freeman felt that since the purpose of the bridge was to cross a wide harbour which often saw some fairly wild weather, the arch shape would be the most stable.
Originally, the bridge's designer, JCC Bradfield, proposed a suspension bridge, then a cantilever bridge, which was the first proposal accepted. After that, Bradfield turned his sights towards an arch bridge, after travelling overseas and seeing the developments in light steel which made a steel arch bridge such a possibility.
What is the maximum weight a bridge can hold?
Probably 3 to 10 times the weight you plan for it to carry.
Will the bridge be only for people? For cars? For Trains?
How long and how wide will it be? The longer and wider it is, the more people, cars, etc. that will fit on it.
What are the four main parts of the suspension bridge?

When was the Eiffel Tower last painted?
The Eiffel Tower was lasted painted in 2009. It is painted every seven years.

This structure in Paris was built for the 1889 to commemorate the centennial of the fall of the Bastille in 1789.
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 !
Why do you think steel bridges must be painted?
I think they have to be painted because if you do not paint something that is steel than it will rust beyoned repair.
When was the first water dam built?
The decision to build the Water Tower came in 1895, one year after a severe water shortage forced the cancellation of classes. It was the first elevated steel water tower west of the Mississippi. Standing 168 feet above campus, the tank itself was 40 feet tall and 24 feet in diameter and held 162,000 gallons. The use of the Water Tower was discontinued in 1978 when the university switched to a city water system. It was placed on the National Register of Historic Places in 1981, and in 1987, it was restored. In 2007, the American Water Works Association presented an award to Iowa State University, naming the Marston Water Tower, an "American Water Landmark."

How was rainbow bridge formed?

How many bridges are there in the us?
According to the 2006 Bridge Inventory issued by "Better Roads", there are close to 600,000 bridges in the US. This includes all bridges of 20 foot or greater length that carry roadways open to the public. It does not include railroad bridges. Other interesting fact: according to the same report, close to 25% of all bridges are either Structurally Deficient (SD) or Functionally Obsolete (FO).
Per the Federal Highway Authority (FHWA): "An SD bridge is one that (1) has been restricted to light vehicles only, (2) is closed, or (3) requires immediate rehabilitation to remain open. An FO bridge is one in which the deck geometry, load carrying capacity (comparison of the original design load to the State legal load), clearance, or approach roadway alignment no longer meets the usual criteria for the system of which it is an integral part."

How does a beam bridge support a load?
Beam bridges are the most simple of structural forms being supported by an abutment at each end of the bridge deck. No moments are transferred throughout the support hence their structural type is known as simply supported.
The simplest beam bridge could be a slab of stone, or a plank of wood laid across a stream. Bridges designed for modern infrastructure will usually be constructed of steel or reinforced concrete, or a combination of both. The concrete used can either be reinforced, prestressed or post-tensioned.
Types of construction could include having many beams side by side with a deck across the top of them, to a main beam either side supporting a deck between them. The main beams could be I-beams, trusses, or box girders. They could be half-through, or braced across the top to create athrough bridge.

Because no moments are transferred, thrust, as from an arch bridge, cannot be accommodated, so leading to innovative designs, such as lenticular trusses & bow string arches, which contain the horizontalforces within the superstructure.
Beam bridges are not limited to a single span. Some viaducts such as the Feiyunjiang Bridge in Chinahave multiple simply supported spans supported by piers. This is opposed to viaducts using continuous spans over the piers.
Beam bridges are often only used for relatively short distances because, unlike truss bridges, they have no built in supports. The only supports are provided by piers.
The Tacoma Narrows Bridge crosses the Tacoma Narrows of the Puget Sound, it collapsed in 1940.
