This bridge type has straight cables connected to a tower. Its best use for long distances and preserving envornment. This may use only one tower and it cost less than suspension

• A. Cantilever Bridge
• B. Arch Bridge
• C. Cable-Stayed Bridge
• D. Suspension Bridge

Answer: (C)

Cable-stayed bridges use straight cables that run directly from towers to the deck, forming a fan or harp pattern. This load path lets the deck be supported by many cables tied to one or more towers, so you can span long distances efficiently without the huge main cables and anchorages required by suspension bridges.

Why this fits the description: you can achieve long spans with relatively few towers—sometimes just one—making construction simpler and often cheaper than a suspension bridge. The shorter, direct cable paths also tend to involve less extensive foundations and fewer offshore works, which helps minimize environmental impact on the waterway and surroundings.

So, the bridge type described, characterized by straight cables connected to a tower and suitability for long spans with potentially a single tower at a lower cost than suspension, is the cable-stayed design.
