What is the typical lifespan of a traffic signal pole?

The typical lifespan of a traffic signal pole is around 20 to 30 years. This estimation takes into account factors such as material durability, environmental influences, and maintenance practices. Traffic signal poles are generally constructed from materials like steel or aluminum that are engineered to withstand various weather conditions, corrosion, and physical impacts. Over time, even with proper maintenance, there can be gradual wear from environmental factors like wind, rain, and exposure to chemicals, which can affect their integrity.

Choosing a lifespan of 20 to 30 years reflects a balance between durability and the need for periodic inspections and maintenance to ensure they remain structurally sound and operational. This lifespan encourages proactive management and replacement strategies for municipal agencies responsible for traffic safety and infrastructure.
