They haven't mentioned any name for 418 yet.

So if I understand it correctly, the Mill Road underpass will be replaced at its current alignment and hence will have to be closed, but Union Road underpass will be on a different alignment and will be constructed while the current one remains open?

This one also appears to be concrete paving. Sounds like few years down the road we will have concrete pavement all the way from Windsor to London (except for that small patch between highway 3 and Walker Rd).

I don't think the work at either Mill Road or Union Road are structural replacements, instead they are just rehabilitation projects.

I'd guess the full closure of Mill Road is just to ease construction staging on what is otherwise a pretty low-traffic road.

As per http://hwy401reconstruction.ca/about-part-b/ (if you scroll down), it appears both those underpasses will be replaced.

from the website, emphasis mine:

Quote:
The reconstruction of approximately 10.4 km of eastbound and westbound lanes of Highway 401 from 1.4 km west of Union Road to 0.3 km east of Southminster Bourne
Drainage Improvements including the replacement of non-structural culverts and sewers
Site #5‑49/1 CNR Overhead Bridge, Temporary Repairs*
Site #5‑49/2 CNR Overhead Bridge, Temporary Repairs*
Site #5‑50 Union Road Underpass, Superstructure Replacement
Site #5‑294/C Baird Creek Culvert Replacement
Site #5‑2 Mill Road Underpass, Superstructure Replacement
Site #5‑296/C Lewis Creek Culvert Replacement
Site #5‑3/1 Dodd Creek Bridge EBL, Structure Rehabilitation
Site #5‑3/2 Dodd Creek Bridge WBL, Structure Rehabilitation
I would interpret superstructure replacement to mean a deck replacement. These aren't full bridge replacements.

That is more in-depth bridge work than I had expected though. I would have figured that they would have just done barrier repairs, abutment replacements ect. Aside from Hwy 40, this is the most in-depth bridge work to have been conducted along the corridor between Tilbury and Windsor.

Interesting, I didn't realize that had a different meaning. Good to know.

Why are they making the surface concrete off late? It's not as smooth as asphalt and it's not good for tires or noise mitigation either.

Probably its long lifespan, and noise isn't an issue on roads way out in the middle of nowhere (even when the area builds-out, the ROW is so wide...)

It's a well established fact that concrete lasts longer but they never chose to use it that much for the surface. What has changed now? Has concrete become cheaper or have maintenance costs increased making asphalt roads expensive to maintain?

Not sure why they are using concrete now, but having driven on the sections of the 401 that were recently reconstructed with concrete, I prefer driving on concrete over asphalt. Primarily because it doesn't require maintenance every 10 years. I am quite excited to see concrete all the way from Windsor to London.

Superstructure means everything above the bearing level (i.e. new girders and deck). MTO uses that term internally, so I would assume its the same for advertising.

The MTO has begun an EA to look at upgrading and widening the 401 through Belleville:

The key in this area is Highway 62 passing right through the centre of town. It crosses Moira River twice, and is through a heavily built up area. If they are planning on twinning the Norris Whitney Skyway, that potentially would be twice the traffic going through Belleville streets.

They should eithe;
Re-sign
  1. highway 62 going along Dundas (former highway 2) to Wallbridge Loyalist Road (then concurrent with 401 until it continues with 62 to the north), or
  2. Build the new bridge roughly as a continuation of Wallbridge Loyalist Road to the "island".
The second option would require a bridge about twice the ~900m of the current bridge - which would be close to twice the cost - which on this bridge is close to $100M extra. I'd say the first is preferable.

For those who are curious, I found these water depths in the area. http://fishing-app.gpsnauticalcharts....1162/-77.4632

Would it be correct to say that this is not a continuation of the 6 laning in Kingston area? Is there a separate EA for widening between this study area and the 6 laning in Kingston?

^ This section would be independent of the 6-laning in the Kingston area.

The Belleville section really sucks, and there's enough space for 6, narrower lanes but... if they're rebuilding something like Kingston would be rather desirable.

It would be sad to see one of Ontario's last cloverleafs be replaced though

Clover leaves are really dangerous at highway speeds if the ramps exit or enter right from the highway. Those on I-94 en route to Chicago drive me crazy.
