Talk:Parclo interchange
From Wikipedia, the free encyclopedia
AB3 seems ambiguous - is it meant to cover both distinct possibilities (up to rotation)? --SPUI 02:26, 8 Dec 2004 (UTC)
- Hmmm, google searches for "parclo ab-3" and "parclo ab3" give nothing. Is this term actually used by the MTO? --SPUI 02:27, 8 Dec 2004 (UTC)
- Actually, there are actual Parclo AB3s in Ontario, though I don't know if the MTO calls them as such (they do use the term Parclo A3 and Parclo AB, however). The example I listed there is almost identical to the interchange between the Queen Elizabeth Way and Ontario Street in St. Catharines. Now that I think of it, Highway 416 and Hunt Club Road in Ottawa is also a Parclo AB3. Of course, the difference with these two examples is that side streets are also integrated into the actual interchange. Same principal, just looks a little different.

What does Ontario call a parclo with only one loop, like [1]? --SPUI 02:59, 8 Dec 2004 (UTC)

- Good question. They're all over the 401 in Durham Region. I'll hunt down the official designation, but I think they're called something along the lines of Half Parclo/Half Diamond Hybrids. As for Parclo AB3, it -is- an actual designation under the Ontario System. There are also Parclo A3s along the QEW in Niagara (At Seventh Street in St. Catharines, and Mountain Road in Niagara Falls). You can more or less ad any combo of A, B, 2, 3 or 4 to make up a designation for them. Snickerdo 03:10, 8 Dec 2004 (UTC)
Not only used in North America - junction 1 of the M50 motorway (United Kingdom) is a parclo. Loganberry 13:48, 19 May 2005 (UTC)
I'll leave this to someone else to investigate, but this appears to be another example of a B4 interchange in Ontario. It doesn't occur on a 400-Series freeway (it's the easternmost interchange on the full freeway portion of Ontario provincial highway 17 in Walden, with RR 55), but nonetheless. --Scani71 04:50, 14 April 2006 (UTC)
