Can you elaborate? I'm seeing a bunch of options, not picturing it too well though.
Yes, sorry. It mostly concerns Parcel 12 - that's the ramp in full view of Quincy Market with the curved wall alongside the ramp, unkempt grass and off-and-on photography installation. Just briefly on the others:
Parcel 18 (Rowes Wharf) is surprisingly rather OK despite the ramps, because of a clearly defined public room that just somehow works. The ideas in the document here won't change anything radically but they may help enclose the space still further. That's good.
Parcel 6 (Sudbury, New Chardon) is a lost cause. The proposal in the document makes some sort of plaza and pedestrian pathway across new ramp ceilings. Maybe there's a better idea out there for this one, but I'm not sure.
Okay, back to Parcel 12. The document here proposes a mini High Line (groaaaan) to weave pedestrians diagonally up and over the ramp. But I have a much better idea in this case which I think warrants study:
remove the ramp. Specifically, remove the southbound offramp to Clinton@Surface - the ramp that makes the parcel completely unbuildable. Remove that ramp and you now have a very solid rectangle footprint for a building, which would be very important in this location to pull the urbanism of Quincy Market out towards the North End.
Why do I believe this offramp is unnecessary? Because consider where southbound artery traffic is coming from. If they're coming south on 93, they can use the Leverett Connector and Merrimac/Congress Streets to get to this general area. And, if coming from the west on Storrow, they can access this part of downtown through either the Cambridge Street exit or through Leverett Circle to Merrimac/Congress Streets. The point is that in both cases the traffic would be redirected to another nearby exit.
