How do you solve konigsberg bridge problem?
Leonhard Euler proved that the problem has no solution.
What are the advantages and disadvantages of river bridges?
Mainly for transportaion/commuting. The downsize is when the river swells. A town near where I live had two (2) bridges to access it here in Arizona. They both were washed away during monsoon and the town was officially declared an "island" for a short while. All 3000+ residents had to be evacuated by helicopter...luckily the waters did not rise too much
How are the streets arranged in New York?
The streets of New York City are arranged on a grid pattern, except for Lower Manhattan. Lower Manhattan is the oldest part of New York City, and its streets were formed long before the urbanization of the remainder of Manhattan.
The strongest bridge in the world?
Arguably the longest bridge is the Bang Na Expressway, in Bangkok, Thailand. It is 33.5 miles long (54 km), but is not considered a bridge because it does not cross a single body of water, instead crossing a river and canals.
The longest bridge running over a single body of water in the world is now the Jiaozhou Bay Bridge in China. 42km in length, it links China's eastern port city of Qingdao to the island of Huangdao. The bridge cost over $1.4 billion to build and was completed in mid-2011.
Other record-holding bridges:
The longest bridge in the world for many years was the 36km-long Hangzou Bay Bridge, which opened in May 2008. The record-breaking bridge has main cable-stayed spans of 448m and 318m.
The world's longest bridge used to be the Confederation Bridge. It connects the Canadian province of Prince Edward Island to the province of New Brunswick. The 12.9 kilometre long bridge was the world's longest road bridge, crossing ice-covered water. It was opened to traffic in 1997.
The longest suspension bridge in Japan and the world is the Akashi-Kaikyo Bridge, completed in 1998 at a length of 1,991 metres.
The world's longest footbridge is believed to be the the Capilano Suspension Bridge, which crosses the Capilano River in Vancouver, British Columbia, Canada. This footbridge is 136m or 446 feet in length, with a height of 70m (230 feet) above the canyon.
How long is the longest arch bridge in the world?

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.

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.

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 !

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 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."
