Crews are working to determine the cause of a newly formed sinkhole in the north lane of Rideau Street near Sussex Drive, which forced rush-hour traffic and bus services to be rerouted Thursday afternoon.
The hole, a few metres wide, is located in the same area where a massive sinkhole formed on June 8, 2016, causing a gas leak, building evacuations and closing the street down for months.
OC Transpo is warning riders there will be system-wide delays on several routes because of the Rideau Street closure. Rideau Street is now closed from Sussex Drive to Dalhousie Street to accommodate emergency repairs.
