Tour de l'Île to close West Island, west end streets this morning

About 25,000 cyclists are expected to take part in this Sunday's Tour de l'Île, the 35th edition of the annual cycling event that takes over Montreal's streets.

The event, run by the cycling advocacy group Vélo-Québec, is wildly popular with those on two wheels, but not so much for motorists who have to deal with multiple road closures. Dozens of streets in the west end and West Island will be blocked off on Sunday morning to allow cyclists to ride through car-free streets.

The Tour de l'Île will start and finish at Mount Royal Park, but cyclists will be able to choose between two separate itineraries — one which will take cyclists on a 65- or 100-kilometre tour right around the western half of Montreal Island:

There's also a shorter route (25 or 50 kilometres) which will take cyclists through Côte-des-Neiges, NDG, Lachine, LaSalle and Verdun:

The road closures are expected to be in effect early on Sunday; the event kicks off at 7:15 a.m. at Mont-Royal Park, and is expected to wrap up completely by a little after noon.
