UPDATE: Papineau station has reopened. [Reopening - Papineau métro station] 🚇🚌✅ Since the emergency work has been successfuly done, Papineau métro station is now reopen. Bus service is also back to its regular route. pic.twitter.com/cQGHtUQuOx— Ligne Verte (@stm_Verte) May 24, 2019 Montreal's STM Green line has had a rough week this week. On May 17, the entirety of the blue line was shut down for over 8 hours. That same week service on the green line was interrupted twice. The first closure was due to water infiltration, while the second closure was shut down due to the presence of smoke. The STM has just announced that they have currently closed the Papineau metro station. They state that they are doing temporary construction work which has closed the station. This closure was unplanned. Earlier on Friday, the STM published the Tweet below: [Fermeture de la station Papineau] 🚇⚠️ Des travaux temporaires au niveau de la mezzanine entraînent la fermeture de la station Papineau. La navette 815 fait le trajet entre les stations Berri-UQAM et Frontenac. Référez-vous au plan de quartier ⏩ https://t.co/Abf0OiPcgC pic.twitter.com/z3SplUzn07— Ligne Verte (@stm_Verte) May 24, 2019 The Tweet reads "Temporary works at the mezzanine level have led to the closure of Papineau metro station. The 815 shuttle is travelling between the stations Berri-UQAM and Frontenac. Refer to the neighbourhood map."

This means that the the green line is currently closed between Berri-UQAM and Frontenac: a long stretch. [Station Beaudry] 🚇🚧🔨 La station est maintenant fermée jusqu'en juin 2019. La #stm15 Ste-Catherine et la #stm815 Papineau/Berri-UQAM sont de bonnes alternatives pour vous déplacer entre ces stations 👉 https://t.co/FMo3X3cXl9 #stminfo pic.twitter.com/LUehGIjsMZ— Ligne Verte (@stm_Verte) October 3, 2018 The 815 shuttle has been travelling between Beaudry and Berri-UQAM since the closure of Beaudry in October. It has temporarily been extended to go to Papineau. READ ALSO: Montreal's All-New "Free Museum Day" Metro Map There's no specific time frame at the moment. Our team on site is on working hard to ensure a prompt reopening. Thanks!— Ligne Verte (@stm_Verte) May 24, 2019 The STM gives no reason for why this construction led to an unplanned station closure. As of right now, there is also no news on when the station will be reopening. We will update this article as more information becomes available. The STM has stated that they are working on a "prompt reopening." Construction at the Papineau metro station has led to a temporary closure of the station. The STM cites construction work at the mezzanine level for this closure, which was unplanned. It is unclear when the station will reopen.
