At a press conference held earlier today, city officials confirmed that an area affected by cracks in the underground tunnel leading to the McGill metro station will remain closed until further notice. According to the STM, the Green line will be shut down between Berri-UQAM and Lionel-Groulx stations, although Atwater station will apparently re-open on Monday. In the interim, commuters are strongly encouraged to use the nearby Orange line; also, shuttle buses will continue to run eastbound along Sainte-Catherine, and westbound along Réné-Lévesque.

For detailed information about street closures, consult the Ville de Montréal website. For metro service updates, check the STM main page.

UPDATE: At 9:30 PM tonight, Mayor Tremblay announced that full metro service has been restored and that all but one block of de Maisonneuve will be open to vehicular traffic tomorrow. Complete report here.
