L4 Unlock: Ontario - Milton (Ch. Tremaine Rd...)

Hello, to edit the following segments, I need Tremaine and more segments unlocked. Can you assist?

Permalink
Reason: In preparation of the new bridge opening over the 401 (starting Mon, Jul 7), I need to connect the new Tremaine segments to the Campbellville/James Snow/Ligne Dublin Line roundabout, but I can’t do it with JB in the way, which needs to be deleted and re-added afterwards.

I also would like to connect the local roads to the (old) Tremaine segments, this way it’ll be shorter segment to put a restriction and deleting the old overpass once the demolition takes place. + some geometry adjustments.
Unlock to lvl: 3

Thanks in advance,

Shit, the overpass is opening already? Given the imagery I at thought at least another 4 months into fall.

I’ve requested a 1-month update, I suspect we’ll get it soon (at least the road path)
Don’t delete the old overpass until its gone, just use the RTCs

If you can find a project photo, that would be amazing!

Unlike other websites that have under construction interchanges and such projects. There’s none for this one in particular, simply because this interchange is being made by the municipal, and not MTO.
The only high resolution imagery I can find is the one below, which was taken in mid-May 2025.

That’s what I would do in the meantime (I won’t delete it until then), but also checkout any street name changes. I reached out to Region of Halton regarding any name changes, along with road types on the old section. Still waiting to hear their response. Oh yaah, I deleted Ligne Dublin Line segment (near the 401) because that won’t exist any longer now that it’s replaced by the new Tremaine realignment.

Here’s some of the new segments for relock, along with approving this suggestion because that segment likely failed to highlight for the unlock. But the rest should stay as L3 until we get a new imagery for any geometry adjustments/the new bridge opens (which I thank you this time for requesting it since this was a bad stopping point for the newest imagery that came in earlier this month), and also for the old bridge demolition to delete one segment.

thats fine, was more for LG, and thats more than enough!

Not super liking the bowtie south of Peru, its complicating what would be 2 segments into 5 segments - but can leave it for now

Segments relocked - please mark thread as resolved. We can deal with future requests in new thread.
