Skew arch bridges of up to 45 degrees are not uncommon and many even exceed that figure. There's a helicoidal skew arch in the U.K. that was built of stone in 1830 to carry the Haggerleazes branch of the Stockton & Darlington Railway over the River Gaunless, which has a skew angle of 63 degrees. In other words, instead of crossing the river at the normal 90 degrees, the railway and river cross at 27 degrees. (90 - 27 = 63)
There's a skew arch bridge built to a different principle (it's called a ribbed skew arch) in Harpenden, Hertfordshire, UK that carries the Midland Main Line across Southdown Road at an angle of only 25 degrees, giving the bridge a skew angle of 65 degrees. That's the most skewed arch bridge I know of but there may well be others and if so I'd like to know.

Arch bridges are in the shape of an upside down "U" with mainly steel beans, while supension bridges have one or two Major verticle beams with strong wire connecting to the bridge.

A truss bridges are designed using materials that are connected in a manner to be stressed under tension and/or compression. I truss system can be designed to be as long as necessary. Columns are also used in truss desins to reduce deflections.

building an arch bridge takes time.. depending on weather or climate. most bridges are completed between 10 to 15 years.
An arch will stand most force.
truss bridges are able to support the most weight applies to the bridge, especially when the weight is applied to the middle
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.

The Pont-Neuf (New Bridge) which is despite its name, the oldest bridge in Paris, and the Pont Alexandre III (opposite the Invalids) with its magnificent lamp posts are certainly among the most famous.
