Can anyone think of other roundabouts in the GTA? There aren't many, I can only think of two really small ones in rosedale for Toronto.
Now that I think of it, there are a few multi lane roundabouts at the newly reconfigured Holt Road interchange in Courtice, so I guess hwy 48 won't be the first. Probably the largest though.
the only major arterial roundabouts I can think of: (there are lots in subdivisions on very low traffic streets around the GTA)
- Holt Road / 401, Courtice ( 3 roundabouts)
- Tenth Line, Stouffville (2 roundabouts)
- York/Durham line and Durham 5, Stouffville/Pickering
- Concession 6 and Durham 8, Uxbridge
- Keele and Lloydtown Aurora Road, Aurora
- Tremaine Road, Milton (4 roundabouts)
- King Street and Coleraine drive, Bolton
- Emil Kolb Parkway and Highway 50, Bolton
