I like the idea, but that specific corral is hard to use because of the chain across the road. You have to ride up on the sidewalk and (going east) dismount to lift your bike or scooter up to the sidewalk. Not a complaint about the corral but the poor way the street was blocked off. Bollards would be better.

Really glad to see this is being proposed! I bike between My Vernon and Federal Hill often, and getting to and from the end of the cycle track on Cathedral is dicy.
