It's the one time of the year when Ontario drivers can vent their frustrations off the road.

The Canadian Automobile Association launched its seventh annual Worst Road competition on Wednesday, urging motorists to vote for the street that gives them the most problems.

Potholes, constant traffic and construction are often the most popular reasons why drivers will nominate a roadway as being the worst in the province.

CAA and officials from the Ontario Road Builders' Association will officially launch the campaign Wednesday at 10 a.m. by talking to reporters about the cost of bad roads, bridges and highways to taxpayers and the need for municipalities to make infrastructure funding a priority.

"People know that when they hit a pothole, they have to replace their tire and rim, it can be quite costly," said Faye Lyons, CAA spokesperson.

She estimated the cost could hit $400 if a car suffers damage to its suspension.

Lyons launched the campaign and spoke to reporters at the corner of Steeles Avenue and Bathurst Street -- a stretch of road that has long been at the top of the Worst Roads list.

Last year, Steeles Ave. won the honour of being voted the worst road in Ontario.

There's still a lot more work to do on Steeles Avenue, Lyons said, but so far the campaign has been a success, resulting in 90 per cent of the roads listed in the top 20 being fixed.
