The installation of bridge guardrails is for the safety of pedestrians. We must adhere to relevant regulations regarding the installation height of guardrails, as both excessive or insufficient heights pose safety hazards. Let's take a closer look at what the appropriate installation height for bridge guardrails is.

What is the appropriate height for bridge guardrails installation?

1. Height: The railing height on the sidewalk or the outer side of the safety belt should not be less than 1.10 meters. The clear spacing between railing components should not exceed 140mm, and horizontal line railing should not be used. The railing structure design must be safe and reliable, with the base of the railing set with anchor bars that meet the strength requirements of relevant specifications.

2. Strength; the railing should withstand a collision at 80 km/h with an angle of 15 degrees without the vehicle falling into the river.

3. The railing design and color should harmonize with the surrounding environment, and landscape design is recommended for significant bridges.

When bridges cross major traffic routes such as expressways, urban rail transit, highways, and main railway lines, protective fences should be installed on the bridge sidewalks' railing. The height of the fence should not be less than 2 meters, and the length should be equal to the width of the road below and extend 10 meters beyond each side of the road.

5. The vertical load acting on the handrails of the bridge pedestrian walkway栏杆 should be 1.2 km/m, and the horizontal outward load should be 2.5 km/m.
