The 401 - Page 55

The current project from Milton to Mississauga is progressing just about as fast as a highway can be widened. It's actually impressive how quickly they have built around the existing roadway.

Once the current Milton to Mississauga project is finished, I'd expect that the Tremaine Road interchange will be constructed immediately to the west of the current project. Beyond that, I'd expect there to be several years before further widening work is completed from Tremain westerly to the Wellington County Boundary.

All of the preliminary work has been completed to widen the 401 through Wellington County, but at this point no engineering work has been started between Tremain and the Wellington County line. Though that said, that project should be starting shortly.

Of interest, the widening of the 401 from Milton to Mississauga is the first stretch of complex freeway along the 401 that hasn't been constructed with a concrete base course. Stone Mastic asphalt has shown increased strength over previous asphalt designs, but it'll be interesting to see how the 401 holds up long term.

I'd agree with the speed of the current construction project, but the previous ones west of the 410 seemed slow AF. When did construction at Hurontario begin... like 2009? Mavis took forever too.

Oh cool- I had no idea an interchange was planned here.
-I'd expect full auxiliary lanes would run from it east to Martin Street so that they don't have to dig up stuff again when the widening is pushed further west.

The last major work needed to Highway 6 would be new overpasses. All the underpasses got widened recently.

The road platform through the Tremaine Road interchange will likely be widened in advance of the widened cross-section, but the Tremaine Road interchange is being funded at least partially by the Region of Halton, so I doubt they will do the MTO any favours when it comes to the 401 cross-section.

Sections of the 401 will need to be widened again through the Highway 25 interchange when the MTO widens the highway westerly to Wellington County. Thank the design-build delivery method for that stupidity.

The concrete poles originally intended to hold up the signals at the Lakeridge off ramp are hilarious to me in that they were actually built and then never used.

sonysnob · #**1088** Posted **Oct 4, 2022, 11:55 PM**

They were used for about a year, and then were subsequently replaced.

The concrete poles are set pretty far back from the intersection so I think the reason they were replaced was that people were running through the stop light from the Lake Ridge off-ramp.

I think that's the reason that the new traffic signal pole is situated directly in the line of sight from an approaching motorist. It's much more visible to approaching motorists than the original configuration was.

Innsertnamehere · #**1089** Posted **Oct 5, 2022, 12:18 AM**

Indeed, just odd that they felt the need to spend extra money for those ridiculous looking poles in the first place instead of just attaching the signals to the main structure like they ended up doing anyway.

sonysnob · #**1090** Posted **Oct 5, 2022, 12:34 AM**

The new setup is still ground mounted as well -- just without the concrete pier. The traffic light standard must be like 30 feet tall.

I think they tried to futureproof the signals by setting the concrete piers as far back as they did so that when they eventually construct the eastbound on-ramp from Lake Ridge they could've left the signals where they were. Too bad that backfired on them.

The Stevenson Road interchange in Oshawa. I've always thought this was a pretty neat interchange:

Neat perhaps, but I've noticed it confuses a lot of people.

I've said it before and I'll say it again.

Six lanes with giant areas of unpaved right-of-way through Mississauga seems like a lifetime ago. Yet it's barely been a decade.

The beastlyness of the 401 defies logic.

Innsertnamehere · #**1100** Posted **Nov 15, 2022, 2:02 PM**

And it just keeps getting bigger. It will go from ~65km of 10+ lane highway to ~84km of 10+ lane highway once this widening finishes, and MTO has plans to eventually expand it to over 160km of 10+ lane highway once the widenings in Durham and to Kitchener are eventually completed..
