DENVER (KDVR) — The spring freeze and thaw cycle is underway, keeping road crews busy filling up potholes.

“If a driver sees or hits a pothole on a state highway, they should report it to one of our customer service representatives so repairs can be scheduled,” Colorado Department of Transportation Division of Maintenance and Operations Director John Lorme said.

CDOT only maintains state roadways, contact city and county public works for repairs under local jurisdiction.

CDOT customer service hotline numbers for each region:

• Metropolitan Denver – Region One: 303.759.2368
• Southeastern Colorado – Region Two: 719.562.5568

• Northeastern Colorado – Region Four: 970.350.2368

CDOT recommends drivers reduce speed if avoiding a pothole is not possible.

Pothole facts and figures from CDOT:

• Average cost: $60 per square yard, depending on hole depth and width

• Stay Alert! Expect the unexpected.
• Watch for workers. Drive with caution.
• Don’t change lanes unnecessarily.
