The real problems are the Brownbelt and the god-awful 50s-style suburban street blobs THAT THE CITY OF OTTAWA CONTINUES TO APPROVE IN THE 21ST CENTURY.

That is why Montreal Road, Bank Street and Wellington/Richmond Road don't follow straight lines.
The fact that those streets are not rectilinear is immaterial; their topology is sound. In fact, there are some suburban areas with perfectly rectilinear street layouts now, but crap topology. Even old European cities, like London, despite the lack of linearity, have excellent street topology. That is what matters, not just for transit operations but for land-use management, street-level experience, and the ability of a city to change over time in response to natural economic and social pressures.

Suburban areas with wasteful and inefficient street topologies are going to bake that wastefulness and inefficiency into the economy and public administration for centuries to come. It is baffling that Ottawa and other cities keep building, and allowing building, in this way.

I'm not sure that's much of an improvement.
Actually, it would be 15-22 minutes. (Walk time + [headway/2])

I think the time savings comes from lower travel time on the bus itself (the bus goes straight down an arterial road and doesn't waste time taking tours of neighbourhoods).

Yep. Even if the increased walking distance cancels out the increased frequency, travel time is still lower.

Anyone know why they are lining the entire Confederation line tunnel with concrete? Is it not bedrock down there? I am a bit disappointed in that (though I bet its good $ for the local concrete firms!), I was hoping for something similar to the Stockholm metro where the bedrock is visible throughout (covered by shotcrete I assume), and concrete is used very sparingly. This results in some cool artwork and lighting effects too!

Wow... impressive.

I'm actually doubly impressed that a city the size of Stockholm (metro pop 2.2m) has 100 Subway stations... 47 of which are underground !!

With Ottawa being located in a significant seismic zone, I'm very happy that the tunnel will be properly reinforced and fully lined in concrete.

Shopowners get one week's notice of three-year Rideau Street shutdown

Vito Pilieci, Ottawa Citizen
Published on: August 27, 2015 | Last Updated: August 27, 2015 8:00 PM EDT


Rideau Street businesses facing disruption with the construction of the $2-billion Confederation Line LRT only learned a week ago that a section of Rideau Street will be closed for three years.

“This is going to affect everyone,” said Corey Hackett, co-owner of Top of the World skateboard shop, which has been on Rideau Street for 23 years. “Every business owner I’ve spoken to in the past few days has been concerned.”

Starting Friday, the busy section of downtown Rideau between Mackenzie Avenue and Dalhousie Streets was to be closed to cars and most buses.

The city says pedestrians will be permitted in most parts of the area, but construction fencing and heavy equipment has shopkeepers worried that will likely mean lost foot traffic. And they question how such a huge project, in the works since 2012, could suddenly require the closure of one of the city’s busiest thoroughfares.

The Confederation Line is not scheduled to open until 2018.

“I don’t think that the city understood the scope of what the construction companies required,” said Hackett.

The city said it plans to work with businesses in the area on a campaign to let Ottawa residents know that the strip will remain open for business, but it’s particularly concerned about how the construction will affect bus traffic.

“Our biggest challenge is not car traffic, it’s making sure there is timely bus operations,” said Rideau-Vanier Coun. Mathieu Fleury, adding that recent lane reductions in the area have caused big issues for public-transit schedules. “It’s one of the key stations along the corridor. What’s important is making sure there is on-time transit.

“We’ve had ongoing discussions. It’s different between discussion and the time when implementation comes. The issue here has been making sure everyone is aware what’s happening starting the 28th.”

News of the street disruption — shopkeepers say they were only notified of the three-year closure at a meeting with city staff officials a little over a week ago — sparked the Downtown Rideau Business Improvement Area (BIA) to request a meeting with the city to try to find a way to ensure that foot traffic isn’t significantly impacted.

The area has been through several rounds of construction in recent years. The building of the Shaw Centre, which started with the demolition of the old Ottawa Congress Centre in 2008, snarled traffic in the area heading toward the ByWard Market.

Lane reductions east of Dalhousie due to more recent construction and the installation of large water mains near King Edward Avenue have also taken a toll.

An $8-million project in 2003 to renew a large portion of Bank Street in Old Ottawa South saw foot traffic to area businesses fall by more than 20 per cent as consumers simply chose to avoid the area. That project lasted less than a year, but several shops ended up closing.

The BIA has asked the city to consider finding ways to open portions of the road during off-peak periods, provide more advance notice about construction and the impact it will have, establish passenger drop-off areas within the construction zone, and to set aside funds for a marketing campaign alerting Ottawa residents to the fact that businesses in the area remain open.

“We’re very concerned, which is why we arranged to meet with city officials as quickly as we could,” said Peggy DuCharme, the BIA’s executive director. “This is what’s going to be, and there doesn’t appear that we will have much effect in changing this. It’s a matter of what can we do that can ensure we minimize impact on our business members and economic viability, as well as our customers.”

According to the BIA as many as 55 per cent of customers arrive at their shops by car. Another large proportion arrives by bus.

“I don’t want people to believe that it’s hell to get down here and it’s an area to be avoided. It’s an optics issue. It’s the continuation of the ongoing construction that’s been going on for years down here,” said Hackett, adding that its not in the city’s interest to see Rideau Street business owners close.

“This isn’t a couple months of short term pain. I don’t think the city’s vision of the first passengers coming out of the LRT at the Rideau Station is that they come out of the underground and are greeted by half of the storefronts being boarded up.”

Ottawa is not in a terribly significant seismic zone.

Can't wait to see more of those ugly red greenhouses get smashed to atoms.

Too bad there is no sign that the new stations will be any better at providing shade than the 1980s red things. Maybe if the people who built the Ottawa transit system had to use the Ottawa transit system during the summer, such considerations would be given higher and proper design weighting.

Depends what you consider to be 'significant' but structural design in Ottawa tends to be governed by seismic considerations, much more so than in Toronto for example.

Actually, Ottawa is a pretty seismic place.

Earthquakes of mag 5-6 are regular, and there is evidence to suggest that earthquakes of up to make 7-8 can happen here as well, both geological evidence (certain landslide scars found in the valley strongly suggest powerful earthquakes created them in the current geological era) and cultural (Algonquin legends about earthquake tragedies).

We're easily the most earthquake-prone city in Canada east of the Rockies.

Remember that earthquake back in 2010? It caused a bridge in Bowman just north of Gatineau to partially collapse, and created cracks in the walls at Parliament Hill.

It's very good that the Confederation Line is properly reinforced against seismic events.

In fact, although most of them go unnoticed, Ottawa experiences over 400 seismic events each year! The Ottawa Valley is a rift valley.

If a big earthquake ever hits, Carleton University is gone. Who builds a university on a swamp in an earthquake zone? lol

I wonder if the St. Laurent platforms will be really wide since the LRT won't require the four lanes that go through there presently.

If I recall, there was also an issue with a main sewer line passing through the middle of the St-Laurent station lower level, so they might opt to keep the platforms in the same location to avoid any work down the middle.

They should put some small shops down there on both platforms to make it a bit less boring and depressing, selling tickets, snacks, magazines, flowers etc.
