Seems like a strange way to 'plan'.
"Oh, traffic hasn't been able to drive on SGR during construction. Hmmm... since drivers are already used to not driving there, why don't we just not let anybody drive there again? It would be cool to have SGR as pedestrian only."
"Yeah... but what about our reputation as a transit-oriented city?"
"Never thought about that. OK, let's let buses on it, but only buses."
"Loud, diesel spewing buses will take away from the pedestrian experience, though."
"Doesn't matter... it looks good on paper."
"What about deliveries to businesses?"
"Well, they've made out fine during construction. But... let's open up the street to traffic overnight so they can't say we're not thinking of their needs."
"Yeah... nobody will care late at night as the only people there will be the drunks coming from the bars."
"Sounds like a plan!"
"Man, that's the best 10 minutes of planning that we've spent all year!"
"Let's take an extra long coffee break to celebrate!"
