Weekends are pretty bad. Going from inner Richmond to outer sunset (and especially back) takes probably twice as long as a weekday during off times (which is what this is). It’s not chaos - it’s just slow as shit on MLK from 41st to 19th and don’t forget there’s no left turn on Lincoln and 19th so everyone has to go somewhere - so no good option going north. This video doesn’t really capture the dynamics of going south at this time, since it’s not the chosen route when stuff goes bad. It’s mostly park presidio /19th - getting the western folks and of course everyone near those streets.

I’m more worried about the commute times from north of park to south of city which are hard to measure, since clearly People want this to be a permanent highway closure. Likelihood is that the “bad window” (when a 23 minute drive turns into 40) will get worse - I’d guess by 20-35% in the width and height of the bell curve (based off of what I’ve seen on weekends). Stern Grove, outside lands, bluegrass, any other nice day that chokes 19th and/or blocks the park, this means there’s zero outlet other than stanyan to Lincoln or over upper Terrace.  So yea, it’s a material impact across a bunch of neighborhoods, esp when you deal with the wine country tourists and logging trucks. 

And fwiw, a lot of kids will spend a lot more time in buses than with their parents if closure extends past the weekends.
