Which element is used to carry traffic over the railway?

• A. Culvert
• B. Tunnel
• C. Over-bridge
• D. Under-bridge

Answer: (C)

Attributing traffic to cross over the railway means the road is placed above the tracks, with trains passing beneath. An over-bridge is built for exactly that purpose: it spans the railway and lets vehicles cross safely without interacting with train traffic. This separation improves safety and traffic flow at crossings. The other structures serve different roles: a culvert handles drainage under the track; a tunnel carries traffic through or under a barrier, not over it; an under-bridge would have traffic go beneath the railway rather than over it.
