==The picture on the right just above is the Confederation Bridge, whose 12.9 kilometre span joins Borden-Carleton, Prince Edward Island and Cape Jourimain, New-Brunswick. It is the longest bridge over ice-covered waters in the world. This historic bridge, which opened on May 31, 1997, helps connect P.E.I. to the rest of Atlantic Canada. The bridge carries two lanes of traffic 24 hours a day, seven days a week, and takes approximately 10 minutes to cross at normal travelling speeds.==

Maintenance workers regularly climb the cable supports to reach the top of the towers. See the photo of the very similar Mackinac Bridge below for a closer look at these support cables.
