If you're planning to dig in Tennessee—whether it's for a fence, garden, or construction—Tennessee 811 is your go-to call before you break ground. It’s a free service that connects you with utility companies so they can mark underground lines and help you avoid hitting anything dangerous. State law requires anyone planning excavation or demolition to contact Tennessee 811 at least three working days in advance to help prevent damage to underground infrastructure and ensure public safety.  Recently John Clark spoke with Tennesse 811's Damage Prevention Liason Jason Fryer for this episode of TENNESSEE MATTERS.
