The Michigan Department of Transportation (MDOT) says that while it's not spring yet, a mid-January warm-up has brought a number of potholes across Michigan. MDOT is also asking motorists to report potholes on an I-, US- or M-route to their hotline.

Motorist throughout the state can report potholes on state highways in three ways: calling the Pothole Hotline at (888) 296-4546; clicking the "Report a Pothole" link here; or by calling your local MDOT Transportation Service Center (TSC) or region office. State Transportation Director Kirk T. Steudle says "the quicker we know potholes are forming, the sooner we can get them patched."

Potholes are most prevalent during freeze/thaw cycles when water penetrates the pavement surface and refreezes pushing the pavement up. Vehicles then push the pavement back down, breaking it and starting a pothole.

Those reporting potholes are asked to provide the route name (M, I or US designation), the county, the nearest community, and the closest cross street or interchange. Potholes on non-state roads should be reported to local road commissions since MDOT doesn't have jurisdiction over those roads.
