‘Ottawa’ First Phase of Concrete Work Complete on Rideau Sinkhole
City officials say crews working on the Rideau Street sinkhole have completed the first phase of concrete work to stabilize the site, while crews continue working to restore services.
The massive sinkhole opened up across Rideau Street on Wednesday morning, swallowing a van that was parked nearby, forcing a shutdown of businesses in the area, and causing commuter chaos that is expected to continue.
An update issued by city officials at noon Sunday said crews worked “non-stop” through the weekend to remove a significant amount of water pooling in a section of LRT tunnel below the site while working to restore services and access to affected businesses along Rideau Street.
Many of those businesses have reopened with full or partial services, including the Château Laurier, the Westin Hotel, Milestones, the Metropolitan, and the Rideau Centre.
Hudson’s Bay and Chapters reopened Saturday morning, along with the popular skywalk that connects both businesses to the Rideau Centre, where crowds of shoppers, and gawkers, lined up for a bird’s-eye view of the sinkhole through the weekend.
City staff continued to work with property owners “on a case-by-case basis to allow them to reopen as quickly as possible.”
Drinking Water Service crews were working to recommission the section of water main east of the sinkhole to restore drinking water to area buildings. Ottawa Public Health was monitoring the work to ensure the safety of the water supply.
Any buildings currently without water service will be under a precautionary boil water advisory once water is restored. The advisory will remain in effect until Public Health officials can verify the water is safe for consumption.
Three buildings remained under a boil water advisory, including:
- 41 Rideau Street (CIBC building — currently not open to the public)
- 45 Rideau Street (Holtz Spa — currently not open to the public)
- 80 Rideau Street
Road closures and restrictions remained in effect, including:
- Elgin Street northbound, reduced to one lane between Albert and Rideau streets
- Rideau/Wellington streets eastbound between Elgin southbound and Dalhousie Street
- Rideau/Wellington streets westbound between Dalhousie and Mackenzie Avenue
- Colonel By Drive/Sussex Drive between Daly Avenue and George Street
Some previously closed streets have been reopened, including:
- Colonel By northbound is open to Daly Avenue
- Colonel By southbound from Mackenzie Avenue is open
- Mackenzie King Bridge between Waller and Elgin streets is open but deemed transit priority and subject to intermittent closures to general traffic as required.
