What’s worse that passing under a crumbling viaduct? How about a crumbling metro tunnel?

The afternoon rush hour promises to be hellish as construction of a bike path on Maisonneuve St. has revealed a large crack on the ceiling of the green line metro tunnel between Aylmer St. and Union Ave. Both the boulevard and the metro line between Berri-UQAM and Atwater have been closed until the fire department can take a look.
