I could go into more details on it all but the short is that for the half block in question the traffic study has been done for “permanent” closure (like Broadway in the city) and those issues are satisfactorily addressed. For example, there are no doors beyond the range of to code fire truck access from the ends of the closure.

A hybrid approach is still much cooler than nothing and I’m so happy to have it, but going full closure stops it from being a street in need of any services like plowing so a lot of the issues stop being a thing when it’s treated as a plaza.
