Tour de l'Ile cycling event happens this weekend

About 25,000 cyclists are expected to take part in this Sunday's Tour de l'Ile, the 34th edition of the annual cycling event that takes over Montreal's streets.

Several thousand more are expected to be on hand for its companion event, Friday night's 23-kilometre Tour La Nuit.

It's also the event that many motorists love to hate, because of all the traffic disruptions and street closures.

Friday night's Tour La Nuit (see the map and the full list of street closures and times here) will take cyclists north from Mount Royal Park to Ahuntsic and Villeray, and then back again.

Sunday's Tour de l'Ile (map and full list of street closures and times here), meantime, will also start at Mount Royal Park, but will take riders east, then north — through Rosemont, St. Leonard, Montreal North and Riviere des Prairies and finally, though the streets of Hochelaga-Maisonneuve all the way back to Mount Royal Park by late afternoon.
