A landslide can put huge pressure on a bridge; if it hits at just the wrong angle, it could lead to major failures. By using curves or angles in their designs, engineers create bridges that handle or avoid landslide impacts better. This results in the faces of the arch not being perpendicular to its abutments and its plan view being a parallelogram, rather than the. Actually, designing bridges is not random at all; there are strong reasons why some bridges don't follow the direct path. At first sight, a curved bridge may look. Bridges serve one basic purpose that of connecting two points that are otherwise disconnected and difficult to access. Generally it provides the shortest distance between the two points. The art and science of constructing these structures rely heavily on the mathematics and consequently the. The Federal Highway Administration (FHWA) provides high-quality information to serve Government, industry, and the public in a manner that promotes public understanding. Standards and policies are used to ensure and maximize the quality, objectivity, utility, and integrity of its information.

Over 150 years after it was completed in 1859, Isambard Kingdom Brunel's amazing Royal Albert Bridge still carries railroad trains 30m (100ft) over the River Tamar, separating Cornwall and Devon in England.
