How long is a DigAlert ticket valid before it expires?

A DigAlert ticket is designed to give proactive notice of excavation work to avoid damage to underground utilities. The validity period of a DigAlert ticket is important because it ensures that the information regarding the location of utilities remains accurate and current. The correct period of validity is 28 days, which reflects the need for a reasonable timeframe for planned excavation activities while also ensuring that utility providers have adequate time to mark their lines. After 28 days, the ticket expires and a new request must be submitted to ensure the safety and integrity of the utility systems in the area.
