Smell of paving tar fills air at Rideau and Sussex

Published on: June 25, 2016 | Last Updated: June 25, 2016 1:34 PM EDT



The pungent, yet welcome scent of hot paving tar greeted pedestrians on Rideau Street near Sussex Avenue Saturday as work crews move to the final stage of repair of the dramatic sinkhole that struck June 8.

Crews have been determinedly working around the clock infilling the gaping pit, as well as pumping out water from an LRT tunnel below the hole.

Despite the encouraging signs on Saturday of paving trucks and rollers, it’s still not 100-per-cent certain the stretch will be open when U.S. President Barack Obama and Mexican President Enrique Peña Nieto arrive in town for the annual Three Amigos summit with Prime Minister Justin Trudeau in mid-week.

Work crews have repaired the damaged infrastructure and service has been restored to all affected businesses.

Steve Cripps, head of the city’s light rail implementation office had guesstimated reconstruction could be complete early next week.

But the intersection can’t reopen until engineers have inspected it and given their sign-off, he added.

“Our target is to open it as soon as we can, but of course safety is our priority,” Cripps said.

The city’s initial estimate for reopening the roads was one to two weeks.

It is a myth that climate change will make our winters warmer (stemming back from when it was misleadingly called global warming). What we will see are more weather extremes so it is quite possible that the number of days below -30 increases.

Furthermore, summer heat is much easier to deal with as simple shading reduces much of its impact whereas cold is kind of everywhere.

The problem is there is so much glass in the stations that instead of providing shade, they will act like a greenhouse.

Huh, I sit corrected. I could have sworn the all time record low was -36C.. perhaps the source I originally read it from was a different weather station.

If you look at the chart, it says that it was recorded in Ottawa, not at the Ottawa Airport. At some point NAV Canada switched the readings to the airport as they needed more accurate weather conditions than Environment Canada was giving them (NAV Canada now provides weather data to EC).

That temperature was probably recorded at 3 in the morning, when trains wouldn't run anyway. In any case, actual temperatures below -30C are very, very rare in Ottawa.

Temperature lows are typically recorded just before sunrise, which in late December (when the low was recorded) is around 7:40 AM. Trains will definitely be running then.

Having said that, the temperature was probably picked because it matched the specifications of the train-set they wanted to buy.

So with the new configuration for Tunney’s Pasture Station now in place, I expect to see a new bridge being built soon. This will eventually be the extension of Goldenrod out to Scott Street. It will run perpendicular to the Transitway across the ‘flat’ section at the top of the ‘angled’ ramp in the following picture:

(from CBC Website)

Goldenrod will be extended over the old trench, just to the west (left) of the word “Closed”, for buses to directly access Scott without clogging Holland/Tunney’s Pasture Parkway. A new set of traffic control signals will be added at Goldenrod/Smirle and Scott. After the LRT opens, this new connection will be made public, but until then it is restricted to buses only.

The Three Amigos will be able to use Rideau Street this week

Published on: June 26, 2016 | Last Updated: June 26, 2016 8:03 PM EDT



Rideau Street is expected to reopen to visiting dignitaries for this week’s North American Leaders’ Summit following repairs to damage caused by a sinkhole earlier this month.

“We were really targeting to get this done before the North America Leaders’ Summit and especially Canada Day,” city manager Steve Kanellakos said Sunday night.

U.S. President Barack Obama and Mexican President Enrique Peña Nieto will be in town with Prime Minister Justin Trudeau for the annual Three Amigos Summit, which takes place Wednesday at the National Gallery of Canada.

Kanellakos wrote in a memo that, as of Sunday afternoon, motorists and cyclists would be allowed to travel east on Rideau Street and turn left onto Sussex.

The city said in a statement that northbound Elgin Street was also reopening Sunday between Albert and Rideau streets, as was eastbound Wellington Street between Elgin to Rideau streets.

The repairs are almost complete, the city said, but southbound Sussex between George and Rideau streets will remain closed to motorists, cyclists and pedestrians. Kanellakos said that northbound Colonel By Drive was also to remain closed. Rideau Street between Sussex Drive and Waller Street also remained closed.

Kanellakos said he anticipates to have the final engineer’s report signed off on by Tuesday, just in time for the visit by the presidents.

He said that a majority of the sidewalks on Rideau have opened, allowing access to businesses in the area before the July 1 holiday that is likely to be one of the busiest days of the year. By Canada Day, the city hopes pedestrians will be able to walk on Rideau, which will be re-opened to OC Transpo buses and taxis on July 2.

On the weekend, the smell of hot paving tar greeted pedestrians on Rideau near Sussex as crews continued to repair the sinkhole.

Crews have been working around the clock infilling the gaping pit, as well as pumping out water from an LRT tunnel below the hole.

“I’m really happy with the progress,” Kanellakos said.

Specific effects of climate charge are notoriously hard to predict, but according to most models, the most likely result for our region is that the overall average temperature rises, but that winter will warm much more than summer will. The region is expected to warm by 3C overall; however, this is most likely to end up being something like 5-6 degrees added to fall and winter temperatures with spring and summer temperatures only going up by 1-2 degrees. So our winters will be much milder but our summers won't be that much hotter.

This has been the trend with the climate change that's already happening:

Look at how the 1961-1990 climate data (http://climate.weather.gc.ca/climate_nor...txtCentralLongSec=0&stnID=938&dispBack=0) differs from the 1981-2010 climate data, just twenty years later (http://climate.weather.gc.ca/climate_nor...xtCentralLongSec=0&stnID=4333&dispBack=0

Here's the average afternoon temperature for each month, in the two data sets:

Month 1961-1990 1981-2010 Increase
January -6.4 -5.8 +0.6
February -4.5 -3.1 +1.4
March 1.8 2.4 +0.6
April 10.8 11.4 +0.6
May 18.6 19.0 +0.4
June 23.6 24.1 +0.5
July 26.4 26.6 +0.2
August 24.7 25.4 +0.7
September 19.7 20.5 +0.8
October 12.8 12.8 0.0
November 4.8 5.5 +0.7
December -3.6 -2.0 +1.6
Annual Average 10.7 11.4 +0.7

The most dramatic increases in temperature were in December and February, while July was almost unchanged.

Applying an increase of 5-6C to winter temperatures is interesting; it pushes all of our winter months to the point where temperatures above zero are typical in the afternoon, and will likely mean the end of consistent snow cover.

Operations for LRT tunnel secret for VIP visits to Ottawa

Jon Willing, Ottawa Citizen
Published on: June 28, 2016 | Last Updated: June 28, 2016 5:41 PM EDT

The city won’t say if it will ever have to close the Confederation Line LRT tunnel during visits by a U.S. president or other VIPs after the $2.1-billion rail system opens in 2018.

A city spokeswoman chalked it up to “security reasons” Tuesday after consulting with the Ottawa Police Service.

Part of the 2.5-kilometre tunnel is under Queen Street, just a couple of blocks from Parliament Hill.

On Wednesday the city is closing downtown streets north of Albert Street as a security precaution while U.S. President Barack Obama meets with Prime Minister Justin Trudeau and Mexican President Enrique Pena Nieto. Obama will be addressing Parliament.

OC Transpo is detouring a few bus routes away from the street closures in the core.

Stephanie Carvin, an assistant professor of international affairs at Carleton University and a former national security analyst, said the city will need to consider how it will operate LRT during a visit by a VIP the stature of a U.S. president.

“We might see an LRT shutdown during future visits. I wouldn’t rule that out at all,” Carvin said, noting the city will need to balance the importance of running the transit system with any security threats identified by law enforcement agencies.

“We don’t want to turn our LRT into Fort Knox,” Carvin said.

Christopher Stoney, the academic director for the new Transportation Policy Innovation Centre at Carleton, said he expects the centre will be exploring these kinds of issues.

Stoney believes the LRT won’t pose a significant threat to visiting dignitaries, particularly since they wouldn’t go anywhere near the rapid transit system. Major cities “do not have the luxury of shutting down the subway or underground for the day,” Stoney said in an e-mail.

The more significant risk would be violence, such as an explosion, underground or along the cavalcade route, Stoney said.

Carvin said the city and law enforcement agencies would work together to assess threats before making a decision on LRT operations.

“It should really depend on the context and what intelligence suggests this is a likely event to occur,” Carvin said. “Usually the most important thing is to provide the most accurate information as to what that threat is.”

The LRT project framework approved by council in 2012 included a “railway delegation agreement” giving the feds authority to take actions in case of security threats.

The agreement also touches on security during construction of the 12.5-kilometre LRT line.

The city wouldn’t say if the North American Leaders Summit on Wednesday will force any LRT-related work to stop in the tunnel. The city, again, cited security reasons.

Rideau Street set to reopen between Sussex and William

Meghan Hurley, Ottawa Citizen
Published on: June 28, 2016 | Last Updated: June 28, 2016 8:43 PM EDT



Rideau Street will reopen to pedestrian traffic from Sussex Drive to William Street on Canada Day following repairs to damage caused by a sinkhole earlier this month, the city says.

City manager Steve Kanellakos said the street was declared safe to reopen by the contractor, Rideau Transit Group, late Tuesday afternoon.

Buses won’t be allowed back on Rideau Street until July 2, after this week’s North American leaders’ summit and Canada Day celebrations.

A majority of sidewalks on Rideau Street have already opened, allowing access to businesses in the area before the July 1 holiday that is likely to be one of the busiest days of the year.

The Metro here in DC doesn't shut down when the President is in a motorcade up above. The Metro also passes under Lafayette Park, which occupies the block directly north of The White House. I would think it's unnecessary to close the Confederation Line due to movement of certain VIPs above. So day to day operations are generally fine here. Certain stations are closed at times for big events, such as the Smithsonian station on The Mall for Independence Day, and the Convention Center station during the Nuclear Summit a couple months ago and during the Inaugural Ball that's held there. The rail lines continued operating through those areas, it was only those specific stations that were skipped/closed.

The used to use the Transitway for the motorcades to go between the airport in Ottawa and the Parliament Buildings. That is why the questions now.

See the pretty little stone bridge on the right of the Lebreton renderings and left of the LRT rendering? There's a road directly above & hiding the bridge in the LRT rendering (Rd is at a different spot on the Lebreton rendering), and it looks like people can enter the station from that road instead.

That makes sense to me. No need to shutdown the line but close access to certain stations if deemed necessary.

Correct me if I am wrong, but this photo from the last construction update looks to me like the section immediately south of Lees Ave., not “Sewer work and grading west of Lees Station”, as described.



(I’m not complaining, since I sometimes get west and east mixed up too, but just trying to ensure accuracy.)
