Ottawa Sinkhole Closes Intersection At Laurier Avenue East And Waller Street

A large sinkhole swallowed up part of an Ottawa street overnight, forcing road closures and the shutdown of a nearby transit station.

It happened around 1 a.m., just south of Laurier Avenue East, the Ottawa Citizen reports. Luckily, no one was injured.

The Waller Street collapse also prompted a shutdown of tunneling work on the city's light-rail transit project this morning. Crews just started tunnelling around the clock in the area on Wednesday.

The city told The Citizen that crews were filling the sinkhole with concrete to stabilize it. At 25 feet wide and 40 feet deep, we're guessing they're going to need a lot of concrete.
