Highway construction work has increased steadily each year, along with concern for the safety and well-being of workers and pedestrians, and the consideration of possible vehicle collisions.
Statement 1: Relevant
The function of barricades and channeling devices is to alert drivers to hazards created by construction or maintenance operations on or near a roadway. They also are meant to guide and direct a driver safely past a hazard.
Highly visible barricades to avoid falling of vehicles in deep interspaces ahead (including drainages).
Statement 2: Relevant
Wire-net provisions are provided to ward off road slippages.
Statement 3: Relevant
Statement 4: Irrelevant
For highway safety, a minor gradient throughout the project is required to improve the drainage system. But signage on the minor gradient is not required as it is not dangerous. Signage is provided for a steep gradient during improvement of the highway.
