A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or railway) without blocking the path underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross.
May 20, 2024 · Bridge, structure that spans horizontally between supports, whose function is to carry vertical loads. Generally speaking, bridges can be divided into two categories: standard overpass bridges or unique-design bridges over rivers, chasms, or estuaries.

Nov 12, 2023 · From Tower Bridge in London to the Göltzsch Viaduct in Germany, these bridges are truly masterclasses in civil engineering.
- Beam. A beam is the simplest (and often cheapest) kind of bridge: a deck, spanning a relatively short distance, held up by a pair of abutments (the vertical supports at either end).
- Arch. Arches are the only kinds of bridges supported entirely by forces of compression. There is some tension underneath an arch, but it's usually negligible unless the arch is large and shallow.
- Truss. One way to extend the reach of a basic beam bridge is to reinforce it—and engineers have found the best way to do that is with a system of diagonal, triangular bars on the sides, which are called trusses.
- Cantilever. Two back-to-back beams extending outward from a pier can balance one another—just as a tightrope walker can balance by holding both arms straight out from her body.
Mar 22, 2010 · The Brooklyn Bridge, which connects the New York City boroughs of Brooklyn and Manhattan, was constructed between 1869-1883 and spans 1,595 feet.

Oct 8, 2019 · All over the globe, bridges come in many shapes and sizes. The humble structure was born by simply balancing a horizontal beam across two pillars. However, as demand grew, wider gaps needed to be crossed and more weight had to be carried. This created the need for arches.
