What is the difference between a hump bridge and a culvert sign?

[ValeriaMarie]

Culverts do not have traffic signs. The main difference between a culvert and a hump bridge lies in their height: structures over 5 meters high are considered hump bridges, while those 5 meters or below are culverts. Below is an introduction to the relevant knowledge about hump bridges and culverts: 1. Function of a culvert: A culvert refers to a drainage channel (water passage) constructed below the roadbed and beneath the pavement in highway engineering to allow water to flow under the road without obstructing traffic. 2. Caution for hump bridge signs: A hump bridge sign is placed before a hump bridge with significant curvature that affects visibility. When you see a hump bridge sign, you should drive on the right side and slow down.
