A concrete beam bridge with supports spanning over a river, under a partly cloudy sky.

Beam Bridges Explained

Ultra-Short Answer A beam bridge is a bridge where the deck is carried by straight beams (girders) supported by abutments or piers. It’s the go-to choice for short to medium spans because it’s predictable, buildable, and easy to scale by adding supports. What To Know In 30 Seconds… Beam Bridges Explained

Arch bridge structure with a large stone arch spanning over a flowing river

Arch Bridges: How They Support Weight

Ultra-short answer: An arch bridge supports weight by turning vertical loads into compression that flows through its curved shape and pushes into its end supports, called abutments. When that internal “force path” stays inside the arch, the bridge can carry heavy loads with surprisingly little bending. Abutments and… Arch Bridges: How They Support Weight

A suspension bridge with tall towers, cables, and a roadway over a river

Suspension Bridges: Structure and Load Distribution

A suspension bridge is a tension-dominated structure where the roadway is hung from main cables that drape between tall towers and terminate at strong anchorages. This layout is not just iconic; it is efficient. When designed well, the cable system naturally finds a shape that carries weight through… Suspension Bridges: Structure and Load Distribution
