The foundation looks at least twice the width of the pier and guideway, which will presumably be centred on top of that foundation. Consider that the nearby construction trailers are wider than a train car.

A couple of shots on my way home through the valley today of the WDCB site, looking west of the path. And then of the DVCB looking towards the future portal.
I'll try for shots from the bridge later this week, weather dependent.

I look forward to my future lightsaber battles on board the line 3 trains over the valley!

A reminder to all that I opposed this routing of the OL for multiple reasons (I wanted it to follow Overlea to Don Mills, preferably underground for a host of reasons, but above-grade at the existing Overlea bridge over the valley.
Now....that reminder because...
The gist is thus, they've managed to make the riverbanks unstable, and its compromising the construction site, so now, they're 'closing the river'. That's not the big deal (the inconvenience); its that they're deploying a coffer dam which means, they will be drying out the river for a significant section and piping it around the work area then back into the river bed.
This and other mitigation works will be using up the contingency quickly, its also not good ecologically.

Any idea which side of the river the coffer dam will be deployed? My Google research leads me to believe it would be put in place to stabilze one side of the river, but maybe they need it on both sides? Allow water to run through the middle with dams on both sides?

Normally, the TRCA blocks the entire flow. That's their past pattern. But the West Don is a lot of flow to pipe, so its possible they'll try to scope more.

Let's watch and see whether this raises public or media eyebrows.
Yet another case study in ML accountability. I will bet a box of donuts that they suppress the whole thing.

They better pray to the gods that there isn't a whatever-number-of-year rain-event while they're at it.

Metrolinx’s historical habits aside, I can understand why they’re worried. That ravine bank is quite prone to landslide, as the mountain biking trails on that sidewall (some of the best in the whole Don river system) have learned the hard way.

Recent construction projects seem to require stripping out every green thing within a hundred meters of the ROW. Could the current project have left more vegetation intact and reduced the instability?

Many of those "green things" are weed trees (non-native) and shrubs. Hopefully, they'll plant native seedling and saplings afterwards. Should be planting them now at the plant farm nurseries now.

Are we one really good rain storm away from the NB DVP being closed by a land slip?

Probably, but I imagine they'd try to sell it as "renaturalizing"
