How high must cable drops be above a public highway or interstate?

Cable drops above a public highway or interstate need to be a minimum of 18 feet to ensure safety and compliance with regulations. This height is crucial for several reasons, including preventing any potential interference with vehicles, ensuring that larger trucks or loads can pass under without risk of damage to the cables, and adhering to industry standards that govern telecommunications infrastructure. Maintaining this clearance helps avoid accidents and ensures the integrity of the service being provided.

While other heights may be applicable in different contexts or for other types of infrastructure, 18 feet is the established standard for cable drops over highways and interstates, making it the correct choice in this scenario.
