Which road surface is made by laying logs side by side over muddy ground?

• A. Macadam
• B. Pavement
• C. Asphalt
• D. Corduroy road

Answer: (D)

A corduroy road is built to cross soft, muddy ground by laying logs side by side across the surface. The logs act like rollers or planks, distributing the weight of vehicles and creating a rough, elevated surface that won’t sink into the mud as easily. The look and function come from numerous parallel timbers that resemble the ridges of corduroy fabric, which is why this type of road gets that name. This method was handy in swampy or wet areas because it could be assembled quickly with available timber, though it’s loud and not as durable as modern paved surfaces. The other options involve stone or asphalt surfaces and aren’t constructed from parallel logs laid over mud, so they don’t fit the description of a road made by laying logs side by side.
