Pothole Repairs Underway

Peterborough, ON – Annual pothole repairs are underway to address road damage caused by winter freeze–thaw cycles. 

Potholes develop as fluctuating temperatures allow water to seep into cracks in the pavement, freeze and expand, then contract as conditions warm. Over time, this repeated process weakens the asphalt. Traffic passing over these areas can cause the surface to break apart, forming potholes. 

Late winter and early spring typically bring increased pothole activity due to melting snow, rainfall and ongoing temperature fluctuations. 

Public Works staff regularly patrol roadways and respond to reported issues as weather conditions permit. High-traffic areas and locations where conditions pose safety concerns are prioritized. Temporary cold patch asphalt is used during colder weather, with longer-lasting hot mix asphalt applied once asphalt plants reopen for the season. 

Approximately 1,028 kilometres of roadway are maintained. While pothole repairs occur year-round, activity increases significantly during the spring thaw. 

Residents are encouraged to report potholes to assist in identifying and addressing issues. 

Reports can be submitted by: 

• Completing the online Service Request form at peterborough.ca/ServiceRequest 
• Calling Public Works at 705-745-1386 

When reporting a pothole, provide the exact location, including the nearest property address or intersection. 

Motorists are reminded to reduce speed and maintain a safe distance when approaching road maintenance operations. 

Protecting Roads During Spring Thaw 

Half-load restrictions on designated municipal roads remain in effect until April 30, 2026. These seasonal weight limits help prevent additional deterioration when pavement structures are more vulnerable.
