I find that very rare on a MTO highway, I don't recall seeing any anywhere but the 410 especially around Williams parkway. It makes a nice fit to the highway.
They do. The Hubbell RLC's on the 410 are starting to get replaced by AEL 125's. It could have even just been a test to see if the Hubbell RLC's could support MTO highway exits. I see them in Niagara Falls,and the St Catherine region but not on the highway.
I know of the Hubbell's on 410 that were replaced with AEL 125's. As of now, it's only three in sequence on the Queen off ramp had to be replaced because they cycled or didn't light. Odd it was 3 in a row.
Between Bovaird and Clark Blvd are where the Hubbell's were put on back in 2007 or something like that. They might just be trying to use MTO standard ramp light fixtures such as the AEL 125 or the OV-25.
