Huge Ice Dam Blocks Humber River, Endangers Footbridge.

Looking upriver from Raymore footbridge.

It begins just south of Lawrence Avenue, a gigantic barrage of ice piling up and blocking the Humber. Water has been forced to go around the ice and flood Lions Park.
The recent thaw has compounded the blocking of the Humber that occurred in January. Large chunks of ice floated downstream as the river rose last week and they have plugged the channel forcing it to flood its banks. This latest pile of ice begins by the Lions Arena and continues south all the way to the dam and fish ladder in Raymore Park.

Halfway between the two lies the footbridge connecting Weston to Etobicoke. Normally, the abutments of the old bridge destroyed in the Hurricane Hazel disaster are visible; now they are buried without trace under tonnes of ice. On Saturday, ice was brushing the underside of the bridge and today, the bridge foundations are underwater and in danger of being washed away.

This comparison gives an idea of the depth of the ice blocking the river:

Here is the almost same view in summer:

Looking upriver; notice the normal clearance of the bridge and one of the now buried abutments.

Is the bridge in danger? My guess is that if there is another thaw soon, there will be added pressure on the foundations, not from ice but from water undermining them.

Unfortunately, Thursday’s forecast is for periods of rain and a high of 6°C.
