Bomber, I'm still confused on your take on Broadway. I guess whether Broadway has anything worth walking to is really a matter of opinion from one person to another. But cost is a factual matter, and I don't understand where you're coming up with a big pricetag if we're only talking about a few curb bump outs and restriping the road from five to four lanes. I've not heard Jeff or anyone else suggest widening sidewalks.
Jeff's reasoning behind angled parking is that it creates a safety buffer between cars and pedestrians.

I can tell you that some people who live downtown have told me they would like to see it become more accomodating to walking and biking. As for alternate north-south routes, I can tell you the city is already looking at converting Oklahoma from one-way to two-way traffic, and that Walnut Avenue is carrying a lot of the traffic into Bricktown that used to primarilly depend on Broadway/E.K. Gaylord.
I'm not saying Jeff Speck is right or wrong here. But I do question those who automatically dismiss his ideas and suggestions.
