Sunday's 23rd annual Oasis Rock’n’Roll Montreal Marathon and Half Marathon is expected to bring a record 32,000 runners out on the streets, and this will mean street closures throughout the day.

The Jacques-Cartier Bridge will be closed in both directions from 4:45 a.m. until 11:00 a.m., so motorists are advised to take the Victoria or Champlain Bridges instead.

The marathon and half marathon will start on the Jacques-Cartier Bridge at 8:30 a.m.

At the finish line in Lafontaine Park, singer Marjo will be presenting the closing concert, starting at 12:30 p.m. 

All roads are expected to be reopened by 4:00 p.m.
