What if Washington St had a side-running transitway between the BDPA Parcel and E Berkeley St?

Color code:
Red: Transitway
Dark Blue: Platforms
Light blue: Ramps up to platforms
The side running transitway for this portion was chosen to make use of the C-Mart Parking lot as additional room to put the 'Herald St/Ink Block' station, to avoid the light rail service needing to wait at an extra light at the tunnel portal, and to keep access to Tufts relatively easy for cars. The platforms at Tufts are further south than would be ideal for an easy transfer to enable ambulances to turn on/off Nassau street from the transitway. All platforms are 225ft long and 14 inches high, and the design sends the transitway into a new portal at the same location previously intended for SL Phase 3. (But would connect to the much shallower Tremont St subway rather than trying to immediately dive 50+ft underground.
In order to fit a bikeway, two travel lanes, the transitway, and platforms there have to be some compromises made. These include:
- Removing a lot of parking. I have to imagine a necessary compromise here would be building more parking somewhere, probably a new garage at/around/under C-Mart. Around 40 street parking spaces are removed north of Marginal Rd and 18 south of Marginal Rd, plus at least a large portion of the C-Mart lot.
- Oak Street gets cut off
- A couple turn lanes get removed.
- Travel lanes are only 10.5' wide, the transitway 22', and the bikeway is only 8'. Some sidewalks are also cut back to 7' (but others are widened). All of these are compliant with relevant regulations and guidelines (as far as I can tell) but they are all a bit on the narrow side.
- The bikeway has very little/no buffer between it and the transitway. This can be somewhat compensated for with bollards and the little concrete 'turtle' things I don't know the name for but it's not perfect.
