Which bridge type is typically chosen for quick construction with standardized elements for simple highway crossings?

• A. Movable Bridge
• B. Beam / Girder Bridge
• C. Truss Bridge
• D. Cantilever Bridge

Answer: (B)

For quick construction with standardized elements, a beam/girder bridge is the natural choice. It uses simple, repetitive components—beams or girders and a deck—that can be manufactured in advance and quickly assembled on site. Spanning short to moderate distances, it typically requires minimal temporary works, so abutments are set, girders are placed, the deck is installed, and the crossing can be opened to traffic with relatively little on-site complexity. The standardized components help keep fabrication time, inventory, and labor to a minimum, which is ideal for rapid projects.

Movable bridges add mechanisms and complexity for variable clearance, which slows construction. Truss bridges offer strength and span versatility but involve more fabrication and precise assembly, not as quick with standardized parts. Cantilever bridges can handle longer spans but require specialized construction sequences and staging, which can delay quick projects.
