What describes the physical characteristics of the Intermediate Boundary Fence?

The Intermediate Boundary Fence is specifically designed as a temporary means of protection for roadway workers and often has particular characteristics to ensure safety while maintaining visibility. A plastic chain fence that is 5ft high effectively serves this purpose by being visible to both workers and oncoming train traffic, while still providing a delineation of the work zone. The flexibility and lightweight nature of the plastic material allow for quick deployment and reconfiguration as needed, making it practical for various work sites.

In contrast, a chain link fence that is 10ft high may obstruct visibility unnecessarily and introduce complexities when it comes to quick access for workers or equipment. A solid wall structure would impede sightlines, limit air circulation, and could lead to safety hazards due to reduced awareness of surrounding activities. A metal bar gate does not fulfill the same role as a boundary fence, as it is primarily designed for access rather than for creating a confined work area.
