The problem with modernizing them is twofold:
1. The right-of-way may not accommodate a high speed interchange
2. Even if there is the land, it is a very complex task to keep a highway moving while building a completely new interchange on top of it. The Turcot Interchange in Montreal is an example I like to use as an example.
There aren't many cloverleafs on the 400-series highways anymore - they've mostly been turned into parclos. The last one I can think of was the 400 at Simcoe Rd. 88, but there might be a few in Eastern Ontario on the 401.

88 is not, as they took out the ramp on the opposite side of both bridges. With the widening project for the 400, that interchange will be closed and rebuilt. It looks like when they are done it might be up to 6 lanes a side.

The Lasalle to Elm south isn't much better. I know with the Maley Drive extension Phase 2, it will be widened to there, but I doubt much ore than resurfacing there will happen.

But when it is moving, it is annoying to have to speed up just after breaking. Mind you, at least it is not like how Quebec does their ramps....
[QUOTE=wave46;8796048
It isn't a loop ramp, but I dislike the 400S to 401W interchange - it dumps all of the traffic onto the Collector lanes of the 401W only, instead of providing direct access to the Express lanes. Bonus points: you're blind to oncoming traffic and then you have to deal with people trying to exit at Weston Rd.[/QUOTE]
All 400 series highways that touch the 401 in the collector/express sections should have on and off ramps to both the collector and express. This is resolved mainly with the 404/DVP.
[QUOTE=wave46;8796048
Then there's the 427 interchange...ugh. [/QUOTE]
From a highway with collector/express to a highway with collector/express.... This is one area they should close off and start from scratch.

Not true. Man of them are headed west because they are new drivers who see that it is slightly shorter. Seasoned drivers know better.

Thee western end is nearly 4km away from the 401. Leave it as is. It sserves the purpose of being a direct highway in and out of the airport.

They don't, but with the way he was saying it, he thinks they do. They do use the bypass to get to the nearest road to their destination.

If you're going from the 400S to the 401E, you have a high vantage point to plan things in advance, provided the 401 is actually moving.

I agree. And they just rebuilt this interchange..

No it is not. The main reason most trucks will stay on Regent is less than a few meters is the truck stop.

If the transports are going to the Sault direct, they often go through the US - enjoying a nice 4-lane highway all the way there.

Like I said, except for the new drivers, who will learn quickly why they are the only ones doing it..
