To help prioritize the work, potholes are fixed in the following order:
- High-speed, high-traffic roads
- Collector roads (bus routes)
- Residential streets

![Illustration with text: Water seeps into the pavement and ground below. Water freezes and expands causing the pavement and ground to shift. Ground thaws and a cavity forms between the pavement and ground.Unsupported pavement crumbles under traffic weight](https://storagecdn.strathcona.ca/files/filer_public_thumbnails/images/tas-unique-pothole-formation-660x350.jpg__660.0x350.0_q85_subsampling-2.jpg)
