Southwestern Colorado Culvert Repairs

About the Project

Approximately 20 culverts are being improved with a new state-of-the-art lining in five different counties, including:

  • Conejos
  • Montezuma
  • Archuleta
  • Chaffee
  • La Plata Counties

The new technology allows for the trenchless rehabilitation of pipes while the pipe is still operational and in place. The liner is pulled into the culvert pipe using a special tool to inflate it so it takes out all the creases and creates a smooth internal surface.
