A broken water main under O'Connor Street has closed multiple downtown streets.
The pipe broke early Tuesday morning at Nepean Street, spewing water onto the roadway.
City officials said the underlying soil and roadbed were displaced by the water from a break in the main. Routine watermain repair is ongoing as the flooding has subsided.
The intersection at O'Connor Street and Nepean Street is closed. O'Connor Street is also closed between Lisgar Street and Gloucester Street. Nepean Street is closed between Bank and Metcalfe.
It's not known how long the water main break will take to fix, or when the roads could re-open.
The city said crews remain on site, preparing to excavate for the repair. The break is directly below a gas main. Enbridge will be isolating the gas main before the repair starts. An asphalt crew will be on site immediately following the watermain repair to fix the roadway.
