What is the vertical radial clearance for spans?

In aerial span design, you must maintain a minimum vertical clearance from the lowest point of the span to the surface below to ensure safe passage for people and equipment and to accommodate sag under load. The standard value used here is 3.2 meters, which provides enough headroom for pedestrians and small vehicles while still keeping installation practical and cost-effective. Clearances smaller than this risk contact during sag or adverse conditions, while larger clearances generally aren’t required unless dictated by specific site conditions such as crossing roads or restricted areas.
