Yes, this is Beacon St in Somerville. If they had just put it on the uphill side, this wouldn't be a problem. Unless you're a pro cyclist or an e-biker, you're not going to match car speeds going uphill. There are far fewer driveways and every single side street is a 100 yard dead end due to the train tracks.

Going downhill (cycle track side), I have no problem keeping up with traffic. During rush hour, I usually end up having to slow down for cars in front, which sucks a lot but that's life.

I'm not sure how expensive this project is (it's still not finished!) but it must be at least a million dollars flushed down the drain. And that's not even mentioning those dumb HAWK lights that will be ripped out because no one knows what to do.
