If you're planning to drive across Toronto this weekend, be sure to give yourself some extra time, because two major highway closures are expected to draw heavy traffic and thousands of cyclists. As part of the event, cyclists of all ages will be pedaling freely along some of Toronto's busiest highways completely free from traffic. All ramps to the Don Valley Parkway will also be closed from Lake Shore Boulevard to Highway 401 from 2 a.m. on June 1, including both north and south DVP lanes. All riders are instructed to get off the highways before 1 p.m., so if you're planning to travel in the mid-to-late afternoon, you shouldn't encounter too much traffic. If cycling isn't your thing, there are also plenty of volunteer opportunities you can choose from to make sure the day runs smoothly.
