Stifle the economy?
Yes, I can. Many resources here: http://www.vtpi.org/tdm/tdm96.htm
Including this quote
"In general, if a corridor has enough vehicle traffic to experience traffic congestion there is enough demand for transit and ridesharing to provide congestion reduction benefits. However, simply operating buses or a rideshare matching service will not necessarily achieve this benefit in developed countries where most households own an automobile, and automobile travel is supported by low fuel prices and free parking. Although owning an automobile is expensive, most costs are fixed, giving motorists an incentive to drive rather than use alternatives. Only by giving discretionary riders (travelers who have the option of driving, also called choice riders) suitable incentives to shift mode can transit and ridesharing achieve their full congestion reduction benefits."
There are a number of examples world wide where removing sections of freeways reduced congestion, reduced air pollution, etc... Keeping in mind it is not in isolation, you have to have other alternatives/improvements, but the notion that the only way out of congestion is more roads is just flat out wrong.
Removing a section of highway will reduce congestion IN THAT location but it will simply either...
A) Move the congestion somewhere else OR
Stifle economic activity by eliminating the trip altogether.
Listen, this is how it works. If you want money for transit then your best bet is to get it from extra toll revenue. The people paying those tolls will only pay them if they see some benefit for themselves in the form of road improvements. It doesn't matter that you don't think it will help as long as the people paying think it does.
So just go with that if you want to have any hope of promoting an idea that will actually fund alternatives. And no, you can't just put up tolls and not improve anything and NO they could NOT have just taken three billion bucks put it into transit and tolled the existing bridge. There would be riots in the street.
So can the rhetoric and work on ideas that might actually be implemented or all you are putting out is hot air.
