Parked cars are in fact part of the physical separation between southbound bicycles and automobiles, in addition to the buffer, if I interpret the design docs correctly. The design resembles Wilson Blvd west of Oak for cyclists heading up the hill. Encroachment (and thus dooring hazard) from parked cars could be a similar issue here if the buffer is not maintained somehow. Otherwise the climb looks more comfortable with the new design than the existing street.
The downhill bike lane does appear to have been replaced with parking. Because surface-level storage of private property is surely the most efficient use of public ROW in a dense urban neighborhood with premium transit options and thousands of garage spaces.
If my travel patterns are remotely representative, this block of Nash will see far more bicycle traffic heading uphill than downhill. It’s my preferred route from Key Bridge to the Wilson-Fairfax corridor, but I have always used Clarendon to Lynn the other direction.
