What is the average tension of the median cable guardrail system?

The average tension does not vary much on the median cable guardrail system since prestressed, 3/4-inch diameter cables are used in all of the systems and the recommended tensions are similar. The ranges of tension vary because of temperature: For example, tension at -10 degrees Fahrenheit would be approximately 7,300 lbs., where tension at 110 degrees Fahrenheit would be 3,300 lbs. The average tension would be based on the average local temperature.
