The bridge complex was built between 1890 and 1895 over the Danube, the Borcea branch of the Danube, and Balta Ialomiței island.When it was completed with a total length (including viaducts) of 4,087.95 m (13,411.9 ft) it became the longest bridge in Europe and the second longest in the world. [2]
Every non-trivial knot has bridge number at least two, [1] so the knots that minimize the bridge number (other than the unknot) are the 2-bridge knots. It can be shown that every n-bridge knot can be decomposed into two trivial n-tangles and hence 2-bridge knots are rational knots. If K is the connected sum of K 1 and K 2, then the bridge ...
The Braga Bridge is a continuous truss bridge. It was the fourth longest span of this type when it was completed in 1966. This list of continuous bridge spans ranks the world's continuous truss bridges in two listings: The first is ranked by the length of main span (the longest length of unsupported roadway) and the second by the total length of continuous truss spans.

The largest canal appears to be the Canal of the Pharaohs connecting the Mediterranean Sea and the Red Sea via the Nile.Opened by king Ptolemy II around 280 BC the waterway branched off the Pelusiac arm of the river running eastwards through the Wadi Tumalat to the Great Bitter Lake on a length of 55.6 km.
The Milvian (or Mulvian) Bridge (Italian: Ponte Milvio or Ponte Molle; Latin: Pons Milvius or Pons Mulvius) is a bridge over the Tiber in northern Rome, Italy.It was an economically and strategically important bridge in the era of the Roman Empire and was the site of the famous Battle of the Milvian Bridge in 312 AD, which led to the imperial rule of Constantine.
The decision to build a bridge around Millau was taken in September 1986, says Virlogeux, who at the time was head of the large bridges division of the French administration.
The world's longest suspension bridges are listed according to the length of their main span (i.e., the length of suspended roadway between the bridge's towers). The length of the main span is the most common method of comparing the sizes of suspension bridges, often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge.
