What bridge doesn t have a cable tray installed

Beam, arch, truss, cantilever, and similar bridges do not have cable trays installed.

Types of Bridges Without Cables

Beam Bridges: These are the simplest type of bridge, consisting of horizontal beams supported at each end by piers or abutments. The deck is held up by the beams themselves, so no cables are required for support. Arch Bridges: The main structural element is an arch, which transfers the load to the abutments at either end.

The arch provides strength and stability without the need for cables. Truss Bridges: Composed of interconnected triangular units, truss bridges distribute loads efficiently through the truss framework. The deck is supported by the truss structure rather than cables.

Cantilever Bridges: These bridges use projecting structures supported only at one end. The cantilever arms hold the deck in place, eliminating the need for cable support. Other Examples: Covered bridges, footbridges, viaducts, and trestle bridges also typically rely on beams, arches, or trusses for support rather than cables.

Key Points

Bridges without cable trays rely on compression, tension, and geometric design of beams, arches, or trusses to support loads. They are generally simpler to construct and maintain compared to cable-supported bridges. These designs are suitable for short to medium spans, whereas cable-stayed and suspension bridges are preferred for long spans.

In summary, any bridge that does not use suspension or cable-stayed systems—such as beam, arch, truss, cantilever, and certain pedestrian or temporary bridges—does not have a cable tray installed.

A side-spar cable-stayed bridge uses a central tower supported only on one side. This design allows the construction of a curved bridge. Far more radical in its structure, the Puente del Alamillo (1992) uses a single cantilever spar on one side of a single span, with cables on one side only to support the bridge deck. Unlike other cable-stayed types, this bridge exerts considerable overturning fo
