It’s pothole season, be prepared

North Bay, ON – March 12, 2021 – It’s that time of the year when the City of North Bay streets are prone to developing potholes.

As spring continues its freeze and thaw cycle, potholes will begin to develop on streets across the city at a quicker rate than normal.  This creates driving challenges, and can become an irritant and eyesore for motorists.

Here is what you need to know about potholes and how the city addresses them.

How they Form

Potholes become much more prevalent during the spring due to the freeze/thaw cycle. Water seeps into cracks in the pavement, saturating the soil underneath.  Temperatures drop and the water in the soil freezes and expands, pushing up the asphalt.  The constant traffic load breaks the asphalt causing surface holes.  Further traffic load and weather conditions continue to cause the granular base to erode leaving the potholes.

Repairing Potholes

The winter and spring seasons typically present issues for crews when trying to patch potholes.  During these seasons pothole fixes are generally only temporary because you can’t achieve a good bond between the pavement and the patch.  As a result the patches deteriorate quickly when subjected to the freeze/thaw cycles, traffic and weather.

Report a Pothole

If you would like to report a pothole, go to or call Public Works at 705-474-4340 or   Please provide a detailed description of the pothole’s location.  The size of the pothole is very important, as those that are large, deep or threatening to traffic are addressed first.
