A 300-metre stretch of the LRT tunnel underneath Rideau Street, where a massive sinkhole opened up this week, is flooded, the city said Friday.

As crews at street level continued working around the clock to fill in the hole and repair damaged utilities, engineers ventured into the tunnel two dozen metres underground where excavation had been underway at the time of Wednesday’s road collapse, which swallowed a minivan and one piece of construction equipment, and caused huge headaches for transit users and businesses in the area.
