They're Filling in the rest of Dixie with LED's I see. This city updated their website saying they will replace all HPS now by July, citing delays in fixture production. Have you seen the new mini fixture variation? This overpass seems about 35 years old, so should be a while for rebuilding.

I notice some roads they left the odd HPS fixture installed as if they couldn't get it off? lol, In the south end, they put their highest output LED's on low arms on powerline poles, they blind ya driving at night! light distribution is a small spot on the road too

Yeah I can see it being complete by July. The 403 overpasses have just been retrofitted too, except for a few. Funny how they left the double median shoeboxs alone meanwhile evverything else is LED or temporary lighting. It looks to me like Hurontario hasn't even begun the LED. retrofitting yet from what I see. Dixie doesn't have much left now either just 2 small sections and between Derry to almost the 401. The Davit poles south of Dundas have LED as well now. Theres definitely more LEDs than HPS in Mississauga now

I wonder when Brampton will do the same thing. Yeah Ive spotted some fixtures that must have been stuck or something. This Model 25 was left. this northbound OVX was left. Theres lots more, I just cant remember where some of them were.

Wow sounds like LEDs are really taking off up there! Here in RI no more LEDs have sprung up since that one interchange RIDOT converted to LEDs.

Yeah in a few citys like joe_347v's and south of mine and m@'s its in progress still. Time will tell when our city goes full LED. A very small number of our total streetlights are LED.

Speak of the devil, tuesday it was all HPS then thursday Hurontario street south of Britannia Road was LED far as I can imagine and Britannia is all LED from Hurontario to Mavis. I finally saw a truck installing them too! Funny thing is all this work used their brightest biggest wafer fixture (depicted in your picture), but some intersections use the smaller streamlined fixture on corners, which baffles me. And it looks like the trend as they currently left the lumes on intersection corners as HPS with this work.

It is really rapid now with the progress. I guess Hurontario is underway now. I think it will take less time to finish than they say they will. At the rate its going I think they can finish by May. Theres a few smaller LED's being used, I don't know what they are thought, they look a little like the GE Evolves. Any more post tops in Downtown Brampton gone LED?

Wow its really catching on like wildfire up there! But back in the days of MV, they were using HPS up there starting back in the late 60s yet they didn't get rid of the remaining mercs and incandescents until the 90s (and even then, there's still a few left, especially in the Niagara Falls area).

I don't know when RIDOT started using HPS here. It was sometime in the 1970s. The state completed their MV-to-HPS changeout in the early 90s. BVE (one of the utility companies that used to exist) had been exclusively installing HPS since the mid-80s or so and completed their changeout in the early 90s, though they still have a couple miss-outs here and there. NECo (the biggest former electric company here; everything got bought out by NGrid in 2000) had been experimenting with HPS since the early 80s but continued to offer both MV and HPS up until the mid-90s when they stopped installing MVs and installed only HPS. NECo completed the HPS takeover in some places and didn't even start it in other places. There are some places where the only HPS lights are NGrid-installed replacements after 2000, as NGrid doesn't relamp MV fixtures, though I think NECo relamped fixtures right up until NGrid took them over.

RIDOT was pretty weird. They had began experimenting with HPS in the 70s sometime and had been spot replacing failed MVs with HPS throughout the 80s I'm pretty sure, But then comes the ealry-mid 90s and they go through and replace all the 70s and 80s HPS lights with new HPS lights in Interstate 95 (the new lights were drop lens M-250R2s for 250W HPS and drop lens M-400R2s for 400W HPS, replacing M-400 split doors, model 25s, Hubbell fixtures, and Westinghouse/Crouse-Hinds HPS fixtures). The didn't replace the already-existing HPS lights on other freeways though, so some L-150s, model 25s, and OVMs exist today. In fact, there's a freeway near my house that originally had all OVSs and OVMs on a relay-controlled system (no PCs) but there's a bunch of spot replacement M-250R2s, M-400R2s, and M-400s for failed OVSs and OVMs.

The alternate LED fixture mississagua now uses is the C.I. LRL4. Don't know about Brampton's LED posttops "pilot project", been too cold for me to get around town. Soon enough I will scout the city.

I don't quite remember when our city converted. My guess if I vaguely remember was somewhere between 1998-2005 . I remember seeing shoebox's on Williams pkwy that were Mercs but that must have been the early 2000s. RI is like Toronto, Torontos first HPS lights were downtown. Aluminum poles with short straight arms with M400A's in the late 60's 70's. Theres a few left today. Failed fixture replacements, im not sure how it happend here aI wasnt even born yet lol

UPDATE: Last night I saw guild electric putting up temporary signals up at both these lights and bridge work is now beginning

UPDATE: For the first time ever, There are temporary lights up at both on/off ramps. They actually have OV-15s for all the lights!!! None of them have PCs. Also at Steeles and the 410 Grey Fortrans and Eagle durasigs along with GE M400`s

Interesting. RIDOT has only ever used temporary lighting once that I can recall. It was while they were building the brand-new State Highway 403 around 5-10 years ago. They had 250W HPS OVFs on short 30" or 4ft cantilever arms on short wood poles with an overhead feed. The lights were 15ft at most off the ground. Just as high as the lowest bridge probably. The OVFs has PCs too, the only time OVFs were ever used with PCs here. Almost always they never had PC sockets and the few instances they had them, they used shorting caps.

Interesting that Brampton had MV for so much longer lol. I believe Toronto converted to HPS in 1992-1995, the MTO in 1990-1992. Not sure about Markham or the rest of the GTA though.

I believe the MTO first used HPS when the 404 was built in 1977. A small number of the original fixtures exist on some overpasses.They used 250w OV-25s with glareshields. Markham started installing HPS in the late 70s too. The original fixtures were Unidor 150/400s and OV-15s. Most got wiped out when went to LED in 2013-2015. As for Toronto they installed HPS along Bloor and Danforth in 1967 . I think most of the original poles and fixtures are long gone ever since the replaced most of them with tapered e poles and AEL 125s. The new lights are either 250w MH or 250w HPS.

This one of the rare times in Missisauga you`ll see OV-15s being used and LEDs coming down

Wait, I recall no mercs in brampton since 1990, and certainly no merc shoeboxes. Model25's discovery that clamshells were on our old Davit poles were probably mercs, and maybe some old downtown brampton high poles, but all those were R37'd or removed in the late 80's

You're memory will serve better because I was so young then lol. I do remember seeing the shoeboxs all lit up white on Williams pkwy by Bramalea road when I was younger. Could have been just starting up too.
