There are several factors that affect the span of control. Some of these factors include capability of workers, geographical dispersion, the amount of tasks required and so much more.
span bridge
A bridge's span is the length that crosses the gap.
The span is the distance between supports. The sum of the span lengths is the bridge length.
I think you probably mean "bridge span" rather than "spam bridge." A bridge span is the part of the bridge between its supports.

A span of gap is something in a gas leak or under a bridge that smokes.
its the span of a bridge for which the cost of building both substructure and superstructure is same....
Tsurumi Tsubasa Bridge has a center span of 890m making it the largest bridge in the world!
Akashi-Kaikyo Bridge, Japan is the longest single span bridge which is 1,991 meters long.
The length of a bridge should be determined by factors such as the span it needs to cover, the materials used, and the design of the bridge to ensure its structural integrity and safety. Engineering calculations and standards are used to determine the appropriate length for a bridge based on these factors.
