If anyone uses the cycle track on 12 Ave, I've noticed Ellis Don using it as a loading zone recently (for this project), and the truck drivers and the flag guys are extremely rude to anyone questioning why they are blocking it off, so I suggest that everyone who notices this call 311 (even if you're just driving by). I've actually had a bit of success with them (311) lately. The cycle lane needs to have a detour set up any time they close it, and it's not cheap to close a traffic lane, so that's why they are just doing it at random instead of following the proper channels. Bike infrastructure needs to be respected in this city, and any cyclist who is affected by this should not just be quiet and go around.
