I say just permanently close Broadway to car traffic and make it pedestrian friendly. Let the shops and restaurants take over the street and sidewalk.

@#2: not a bad idea, some allowance would need to be made for deliveries of course, and a path for emergency vehicles.

I've been advocating to remove most POV's from cities for years, the city should be for pedestrians

@6 Agreed
Why they put car traffic, and above ground trolley on top of below ground light rail, in addition to bike lines and pedestrian traffic all on N-S corridor Broadway is beyond me.
Eliminating car traffic would alleviate some of the crowding.
