Ottawa's multimillion-dollar pothole season is underway, with the recent swings in the temperature bringing the usual assortment of craters and chasms.
City crews will fill in as many as 200 large potholes during a course of the day and use close to two tonnes of asphalt.
City officials say they will spend $2.2-million fixing potholes and a total of $5-million on all road repairs.
Potholes are caused when melt water seeps through cracks in the road surface and freezes when temperatures drop. The freeze/thaw cycle can cause localized areas of the pavement to collapse, sink, or pop out.
CBC reporter Cory O'Kelly found a six-centimetre hole on Bronson Avenue and large holes on Booth Street and Somerset Street, but said it's easy to find damaged roads throughout the city.
A pothole in late January forced the Ontario Provincial Police to close some lanes of the Queensway near Maitland Avenue for several hours on a Friday morning.
The City of Ottawa website says anyone who wants to report road damage such as potholes should call 311.
