Cherry St. is open again, but you have to take Unwin to Regatta due to the construction on the trail area between Cherry and Regatta. No big deal. The bridge on Unwin is also out, but it's easy enough to get a bike over there - I made it over there with a trailer on the back, so shouldn't pose problems.
I hope they fix the Don path soon, I'm really missing the lower section of that trail, and I hate the process of stairs to get to Queen (no-go when I have the trailer on, too).
