The assessment of the 400 system seems perhaps too cheery. Some items:

• Old bridges too low on 400?

In article on 400. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

• very narrow shoulders on inside lane on 400, no room for breakdown in inside lane

Source, might be in 400 article. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

• a lot of bridge abutments look pretty close

Source needed. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

• Despite the sprawl or complexity of some interchanges, "You can't get there from here", incomplete interchanges:
  • 427 South to 401 East (have to take 409)
  • 401 East to 403
  • 403 South to QEW East

This is not really discussed in sources, nor generally an issue for traffic movement (aside from the 403-401-410 interchange in recent years with the westward expansion of the GTA. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

[1]

I've got a link here, I am sure it is not considered a reliable source, but I think you can see the gist of it [2] Feldercarb (talk) 23:19, 2 January 2019 (UTC)[reply]

• some exits are on left, say 401 to allen road.

Generally mentioned in individual cases, especially on 407 article. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

• Several freeway to freeway interchanges feature pretty tight turns (although generally lightly used) -- "cloverstacks" -- looking at you 407/410

Need a source. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

• weird 410 to 10 connector

As above. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

• No overall numbering system, unlike US interstate

Generally not true, nor significant for an intraprovincial network. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

Interstates use even numbers for E-W routes; odd for N-S; N-S freeways generally start from low number (I5) in west and are numbered sequential. "A system". 400 series has no such ordering.

I think Quebec Autoroutes have a similar numbering plan Feldercarb (talk) 17:03, 31 December 2018 (UTC)[reply]

• Wacky 403/QEW numbering (the 407 through Halton should have been 403) leaving the 403 non-contiguous

Discussed in both 403 and 407 articles. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

• the highway from Kitchener to Guelph should have been 407, but apparently will be "new highway 7"

Not true. There has never been an official 400-series number for the planned twinning since its conception in the mid-1960s. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

exactly - it should "logically" be 407, but the planners have done otherwise Feldercarb (talk) 17:03, 31 December 2018 (UTC)[reply]

• "Backwards" guidance signage - "QEW via 427" rather than "427 to QEW"

You need to give a reason why this is significant. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

seems backwards from what an average person might expect; eg I am looking for/expecting to get on the 427, but the sign leads with "QEW"

• Kings Highway markers on 400 series are shown as "Crowns", but road-side markers are "Crown and shield"

The crown is the shield. Intersecting roads use the junction crown (the compressed one), nearby ones use a green crown with "to" above the number... at least that's what they are SUPPOSED to do according to the Ontario Traffic Manual. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

Roadside markers have a "shield" (like a coat of arms) topped with a crown. Overhead markers use just the "crown". Two styles of marker.

In Quebec, I believe the roadside Auto-route markers are exactly the same as the over-head markers. Why does Ontario have two different styles of marker?

You can see it here: Ontario has a "guide" sign (crown only) and a route marker (crown and shield). No other province has two styles, if this website is correct. [3]

• Wasn't the 403 touted as "death highway" for a while?

Yes, discussed in its article under "Controversy". - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

• Carnage alley on 401

Mentioned in the History section of the 401 article. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

• 407 was investigated by PEO prior to opening for design safety

Again. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

three highways had safety issue flagged, therefore "systemic" issue, bad design Feldercarb (talk) 17:03, 31 December 2018 (UTC)[reply]

• High mast lighting on 403 on one side of the road, not down the middle, in Mississauga

Significance? Likely due to light pollution mitigation because the northwest side is a hydro corridor. Need a source though. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

just poor design, my opinion -- think it was cheaper to run down one side, rather than route wires under the medianFeldercarb (talk) 17:03, 31 December 2018 (UTC)[reply]

• no lighting on some urban portions of QEW and 403 in Mississauga

As above. Both answers belong in the 403 article itself. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

I am supposing it is a "systemic" problem in that there is no apparent standard for lighting. QEW in Oakville is lit, Mississauga is not; Toronto isFeldercarb (talk) 17:03, 31 December 2018 (UTC)[reply]

• don't use reflectors or cat's eyes for lane markings

Snowplows. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

• opposing centre lanes often close adjacent (no grass median) -- at night looking into oncoming headlights

Tall wall was designed to mitigate this, generally not a complaint, but please let me know if there are any sources on this! - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

• no reflectors on 7West to 8South flyover bridge in Kitchener (oops freeways which aren't 400 series for some reason)

Aren't they rebuilding this? Likely temporary or unnecessary. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

• might be logical to upload all freeways to province (red hill creek, the linc, gardiner, DVP), but no, we downloaded the QEW to Gardiner

Agreed, but only fantasy at this time. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

• Is the express/collector system really effective? the 407 is 12 lanes in one section without collectors

I'm not sure, it's based on a 1960s technique. I don't believe the proximity of the transfers and exits makes it effective in comparison to say, I-271 in Cleveland (though volumes are incomparable), but that's just a personal opinion. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

I've replied in indents with my signature. I don't disagree with most points, but they are subjective and require a good source to mention on any of the highway articles. More importantly, this article is just a summary of the individual articles for each highway; most of the text is a direct copy of the respective ledes for each article. - Floydian ^τ _¢ 00:56, 11 October 2018 (UTC)[reply]

I think the idea was to indicate there are a number of "flaws" with the 400-system.— Preceding unsigned comment added by [[User:{{{1}}}|{{{1}}}]] ([[User talk:{{{1}}}#top|talk]] • [[Special:Contributions/{{{1}}}|contribs]])

Indeed. My reply was generally to the tune of "provide some references to backup these observations and I'll work them into the article." - Floydian ^τ _¢ 17:53, 21 November 2018 (UTC)[reply]

An editor has identified a potential problem with the redirect Interstate Highways in Ontario and has thus listed it for discussion. This discussion will occur at Wikipedia:Redirects for discussion/Log/2022 April 29#Interstate Highways in Ontario until a consensus is reached, and readers of this page are welcome to contribute to the discussion.
