The City repairs potholes year-round
On average, the City responds to between 70,000 and 90,000 road repairs each year. Winter weather conditions can produce a high volume of potholes. the City actively works to repair these conditions each and everyday to keep the City moving.
During winter months, crews use materials designed for cold, wet conditions to address safety concerns as quickly as possible. These repairs are effective but are more temporary in nature and may have a higher likelihood of breaking down under traffic.
Each spring, once winter weather has ended and temperatures have stabilized, the City undertakes an enhanced pothole repair program. At that time, crews can use more permanent asphalt repair methods that provide a more durable and longer-lasting fix, that residents will see.
Potholes develop when water enters small cracks in the road surface. During winter, repeated freeze–thaw cycles cause water to expand as it freezes, widening cracks and weakening the pavement. When temperatures rise, the ice melts and leaves gaps beneath the surface. Traffic passing over these weakened areas can cause the asphalt to break apart, resulting in potholes.
In late winter and early spring, roads may also feel rougher even where potholes are not visible. This is often caused by freeze–thaw movement in the ground beneath the pavement. As frost forms and thaws, the soil can expand and contract, creating temporary surface unevenness. While this may appear as rapid deterioration, it is often related to seasonal ground movement and will likely stabilize once warmer, drier conditions return.
