It is almost summer in Montreal, which means that it is now the season of construction and festivals. While one of those two things is way more fun than the other, they do have at least one thing in common: causing road closures and detours.\nThis weekend is the Go Bike Montréal Festival, an event that celebrates all things biking. As part of the festival, many streets will be closed on Friday night for the Tour la Nuit and on Sunday for the Tour de l’Île de Montréal.\nThese street closures will also force bus detours and closures. Read on for the list of bus closures this weekend.\nMay 31\n11 - Parc du Mont-Royal / Ridgewood\nno service from 18h15 to 00h15.\n34 - Sainte Catherine\nno service from 8h30 to 23h55.\n46 - Casgrain\nno service from 19h to 22h30.\n815 - Papineau / Berri-UQAM\nno service from 9h30 to 16h.\nFor a list of all of the buses that will be rerouted on Friday, or routes that will have certain stops cancelled or relocated click here.\nSTM\nJune 2\n11 - Parc du Mont-Royal/Ridgewood\nno service from 6h to 12h.\n15 - Sainte Catherine\nno service from 9h to 16h.\n36 - Monk\nno service from 8h30 to 12h30.\n51 - Édouard-Montpetit\nno service from 8h to 12h30.\n61 - Wellington\nno service from 9h to 16h.\n63 - Girouard\nno service from 8h15 to 16h.\n71 - Du Centre\nno service from 8h45 to 15h45.\nREAD ALSO: Getting Around Montreal Is Going To Be A Nightmare This Weekend\n77 - Station Lionel-Groulx / CUSM\nno service from 8h to 12h30.\n90 - Saint-Jacques\nno service from 8h to 13h\n92 - Jean Talon Ouest\nno service from 8h to 12h.\n119 - Rockland\nno service from 8h to 11h45.\n150 - René-Lévesque\nno service from 9h30 to 16h.\n160 - Barclay\nno service from 8h to 12h.\n191 - Broadway/Provost\nno service from 8h30 to 13h.\n715 -Vieux-Montréal / Vieux-Port\nno service from 9h15 to 16h\n815 -Papineau / Berri-UQAM\nno service from 9h30 to 16h\nFor a list of all of the buses with detours or with certain stop cancellations or relocations on Sunday, click here.\nMontreal will be celebrating its love of biking this weekend.
