Anyone knows the 427 extension to Major Mackenzie would open during the holiday season? I've seen the project on Sunday from Highway 7 and it's 98% completed.

I believe it's officially still scheduled for very early 2021, though there were rumours of it opening earlier. At this point I expect it to open at some point in January.

I'll expect Doug Ford to cut the ribbon, as if he did any of the real work on the 427 extension.

I will put the new eastbound Leslie off ramp here since it has to deal with highways than the GO Station, though it does effect the current GO station. There are some photos of it in the GO construction thread, but not with the steel as it wasn't there then.

Curve bathtub steel being used for the new ramp.

The retraining wall is no less than 4 inches away from the stair handrail for the new overhead walkway. The retaining wall is being built using large interlocking precast panel

If you look closely you can still see lots of signs of that expressway in satellite images. Subdivisions designed to back onto it, new subdivisions built on lands the city sold after it was cancelled, etc.

For example, Darlingsbridge Drive curves here to provide for the cancelled expressway to curve up and meet the 401. You can also see some new houses along Manse Rd. that are on some of the lands the city sold.

Portia Street here is also in the former right of way. These two subdivisions are also on former right of way. And this one. And this one. And these ones. This one. This one. And this one.

I always thought all the 400 series highways and some high volume highways are build with a thick concrete base to support trucks and other heavy vehicles. Asphalt is paved on top as the driving surface. When they repave the highways, they just remove the asphalt and that groove surface that everyone hates during construction zone is the concrete base we drive on. The shoulders are just paved with asphalt without a concrete base as they aren't meant to be driven on.
This is not happening on the 401 HOV lanes expansion through mississauga and milton, and there is nothing in the OPSS that states the particular roadway design, that is up to the Contracting Authority.

Maybe they thought that the HOV lanes won't need to hold up as well as the general lanes as heavy tucks are prohibited on them. MTO requires them to hold up for a certain number of years even through I highly doubt they go after them if the roadway fails to do so. Just look at how they do with contracting snow removal and only half the job is done.

The HOV lane expansion is a resurfacing of the entire 401 between RR 25 and Credit River. None of the freeway has a concrete base.

Source: I'm looking at the drawings right now.

Yes - what is the point of redoing the express lanes with concrete? It only delays everything.
