1. What does RIRO stand for? Name two examples in Ontario.
- Right-in, right-out. Highway 11 through Oro-Medonte Township and Severn Township/Gravenhurst and Highway 35/115 are the two main examples.
2. List two SPUIs in Ontario
- The two locations are at 4th Avenue at Highway 406 in St. Catharines and Airport Parkway at Hunt Club in Ottawa.
3. What does the term "parclo" refer to?
- Partial cloverleaf
4. What is the significance of the Thousand Islands Parkway? Name two previous designations of it.
- Was an original alignment of Highway 401 and the 1968 section to the north was the last part of the 401 completed. Yes, it also carried the Highway 2S designation.
5. Where is the first major section of Highway 401 built? What part of it still looks the same from when it was first built?
- Highway 2A is correct. I apologize if the question is confusing, because the bridges in Oshawa are original (as is the Highway 12 bridge in Whitby), but I was looking for the part later downloaded to Toronto, as it still has the old ramp alignment, 4-lane cross section and median ditch as it did in 1940.
6. What is the first highway structure built that still is used by the 401 today?
The Hogg's Hollow Bridge is correct.
7. Name four cloverleafs that have been removed in the GTA in the last 40 years.
Hurontario and QEW
10 and 401
25 and 401
7 and 400
8. What colour were MTO traffic lights up to 1970?
- A dark green. Some installations lasted until the early 1990s, including Highways 10 and 5.
9. Name 5 highways (including suffixed routes) that were completely decommissioned and had at least a segment in the GTA.
Here's a list of them all:
2A, 5A, 7B (Thornhill) 11A, 11B (Holland Landing), 25, 27, 47, 49, 50, 136.
10. What is a "Super-2" Highway? Name two Ontario examples.
- A limited access 2-lane highway, with interchanges and/or intersections, but no private access.
Three Ontario examples are Highway 6 in Caledonia and near Hamilton Airport, St. Thomas Expressway (Highway 3) and Highway 137 (connection to Interstate 81).
