What is the main function of a construction barricade on highways?

The main function of a construction barricade on highways is to protect workers and prevent unauthorized access to work zones. Barricades serve as physical barriers that delineate the construction area, ensuring that traffic stays clear of hazardous zones where work is taking place. By creating a buffer zone, these barricades help maintain safety for both construction workers and passing vehicles.

The design and placement of barricades are essential for minimizing accidents and ensuring that only authorized personnel can enter the work areas. This function is crucial, especially in environments with heavy machinery or active construction activities where the risk of injury is heightened.

While educating the public about road safety, redirecting traffic, and displaying messages are important aspects of highway management and construction, these activities are secondary to the primary goal of protecting those who are actively working on the highway and maintaining a safe environment.
