Which bridge type is exemplified by the New River Gorge Bridge?

• A. Arch Bridge
• B. Cantilever Bridge
• C. Suspension Bridge
• D. Truss Bridge

Answer: (A)

The key idea is recognizing bridge types by how they carry loads and what their main structural element looks like. The New River Gorge Bridge is a steel arch bridge, featuring a large curved arch that forms the primary load-bearing element. The deck is supported by hangers from the arch (as in a through-arch arrangement), so the arch carries the load through compression and transfers it to the abutments at the ends. This arch form distinguishes it from a suspension bridge, which uses main cables and towers; from a cantilever bridge, which relies on projecting arms anchored at one end; and from a truss bridge, which uses a lattice framework of interconnected members. The prominent curved arch is the defining feature that makes this an arch bridge.
