Businesses closed, subway shut as fissures force Montreal to shut downtown

MONTREAL (CP) - A large section of downtown Montreal will remain closed for the weekend after two cracks were found in a tunnel that makes up part of the underground city.

Montreal police widened a safety perimeter Friday night to include several blocks in the city's downtown core after officials felt there was a real risk of a road collapse following the discovery of cracks in an underground tunnel.

Fire chief Serge Tremblay told reporters Friday night that a second fissure was also found, but experts haven't been able to conclude what caused the cracks or how long they had been there.

"It's early to say what are the real risks . . . Our role is to prepare for the worst and I won't say the worst will happen, but in this case, we need to make sure we are well prepared," Tremblay said.

Engineers continued to survey the damage after a crack was found inside an underground tunnel leading to a subway station and other malls from The Bay department store.

The affected area is in the heart of the city's downtown core that includes Montreal's Eaton Centre and hundreds of stores and restaurants. The police perimeter includes several city blocks in an area bordered by Sherbrooke, St. Catherine and Bleury Streets as well as University Avenue.

Montreal's underground city snakes through the downtown area, stretching for kilometres and linking dozens of buildings through an elaborate tunnel system.

Mayor Gerald Tremblay said the problem is in the one particular tunnel and not a widespread problem in the city's sprawling underground network. He urged people to stay away from the area for the weekend.

"The area is closed to pedestrians as well as businesses," Gerald Tremblay said. Traffic is also not permitted in the area, which spans several city blocks.

The part of the subway line which serves Montreal's downtown core will also remained closed indefinitely as the McGill station runs below the tunnel, Tremblay said.

"There are no problems to the structures of the metro system, but the metro will remain closed until further notice," Gerald Tremblay said.

Earlier, Mayor Tremblay visited the area and said there's no immediate danger to the public, but by Friday night, the city made the decision to block off the area.

"The security of Montrealers is our first priority," Mayor Tremblay added.

Police spokesman Robert Mansueto said several other buildings in the area were being emptied in an orderly fashion. No citizens are directly affected by the evacuation order, as the area includes mainly businesses and offices.

Meanwhile, engineers were taking a closer look at the two large fissures in the ceiling of a tunnel that makes up part of Montreal's sprawling underground city.

They are trying to determine whether the street that runs above it will need to be reinforced.

The tunnel runs east to west below de Maisonneuve Boulevard and city engineers were checking to see if there was any fear of the roadway collapsing.

No timetable has been set for how long it will take to evaluate the situation but engineers and fire officials would be working through out the weekend, Gerald Tremblay said.

Several hundred people were forced to leave The Bay on Friday afternoon and a major subway line was shut down as a precaution causing commuter and traffic hassles.

No injuries have been reported.

Employees at The Bay noticed water infiltrating the building's basement level.

Montreal fire department spokesman Aime Charette says when fire officials did an inspection they noticed water leaking from a damaged concrete slab in the ceiling of the tunnel.

Does the subway operator inspect their tunnels on a regular basis as part of their routines after services end every night?

I hope it turns out to be nothing serious... that will really screw up downtown traffic.
Lots of money is going to have to be spent on infrastructure in the next generation.

What I think, based on what I have read, is a water pipe burst and has turned the ground to mud. Hopefully we don't see any major damage, especially to historical buildings.

Cracked Montreal tunnel to be reinforced

Canadian Press

MONTREAL — Montreal officials say a tunnel that links The Bay department store to the underground network in the downtown core was at risk of collapse and will be reinforced.

On Friday, police roped off several city blocks, including Montreal's Eaton Centre, after officials felt there was risk of a road cave-in.

City officials told a news conference today that they will install close to 1,000 supports to stabilize a 50-metre long concrete slab in the tunnel, which links The Bay to the subway line, as well as hundreds of stores and restaurants.

Montreal Mayor Gerald Tremblay says the security perimeter will remain until the slab is stabilized.

He says the subway tunnel has not been damaged, but will remain closed, adding the security of citizens is the top priority.

An area of several blocks, bordered by Sherbrooke, St. Catherine and Bleury Streets, as well as University Avenue, remains closed to pedestrians as well as businesses.

Mr. Tremblay also says no traffic will be permitted in the area.

The part of the subway line which serves Montreal's downtown core will also remain closed indefinitely as the McGill station runs below the tunnel.

“There are no problems to the structures of the metro system, but the metro will remain closed until further notice,” Mr. Tremblay said.

Does the subway operator inspect their tunnels on a regular basis as part of their routines after services end every night?
Yes. The subway operator's name is La Société de transport de Montréal. Approximately one dozen work trains comb the 70 odd Kms of servicable route nightly. This many's needed to fuly accomplish inspections in a period never excelling 3.5 hours while the network's shut for the night.

Initial metro tunnelling was refurbished, which involved closing major segments encompassing many stations weekends on end throughout much of the mid 1990s.

But, hey, I do remember looking at the joint of the slab being examined two weekends ago that made me wonder if something had shifted. There was something seam-ridden about what I spied scurrying along being scooped up by the swarming crowds there. Dismayed, I inperceptably shook my head.

This might show why the city must now commit itself into coursing another metro line through the core.

I mean, what are we going to do, now that we're on the eve of having to thread our way through something like no less than! 1,000 support pillars at McGill?

Errr, this revolution ain't going to be Quiet, huh? (It's about time my trains came!!!)

The province refuses to accord top-notch priority to monitoring changes around its reconstruction sites. Ouest boulevard de-Maisonneuve's being re-done. The cones extend out halfway outward into the five-lane one-way boulevard. Just the very fact that (underpaid) department-store employees ended up being the ones who must raise the alarm; I just hope they also got to raze Quebec complacency while they were haggling out preventive response measures with the associated authorities.

Montreal's downtown core returns to normal

MONTREAL — Commuters and shopkeepers in Montreal's downtown core are getting their routines back to normal after cracks in an underground tunnel shut down the area for the weekend.

Most commuters said Monday they had no fear as their subway pulled into a station near where the long cracks where seen on Friday.

“If they say it's OK, I presume it's OK,” said Carol Adams, a customer service representative. “Whatever happens, happens.”

City crews worked feverishly during the weekend to put in between 600 to 1,000 support poles to shore up the tunnel against the risk of collapse.

Montreal Mayor Gerald Tremblay has declared the area safe although permanent repairs are still needed.

Business owners in the area felt the pinch and are evaluating their losses.

“I lost two days,” said Meng Meng, a magazine store owner. “After two o'clock Friday afternoon there weren't many people.”

The key part of the downtown commercial district was closed Friday after officials feared a street would collapse.

The fears arose after the discovery of cracks in a tunnel leading from The Bay department store to an underground mall and subway station. The Bay reopened for business Monday morning after being shut since Friday afternoon.

So where are these 600 to 1,000 support pillars located? The media for days now keeps saying the risky structure is a tunnel linking the Bay to McGill station, but I didn't see one of them when I passed there under- and overground last night.

I think the risky slab that keeps getting reported is one over the metro (train) tunnel adjacent to the east end of McGill station, yet media interviewees the past few days keep iterating that the safety of any metro tunnel has not been compromised. Foul!

Anyhow, this whole mess just goes to show how the city and the province have no well-founded inspection programme in place when conducting reconstruction. Adopting the practice of having an on-duty inspector who can monitor outcomes of reconstructive activity is critically necessary. Figuratively-speaking, we're still many years away from any decline in seeing teams of Quebec roadworkers more often gathered about leaning away on their shovels.
